Can an Algorithm Replace Your Spinal Cord? | IdeaFeed | Big Think

Viterbi Algorithm: kink

Researchers at Northwestern University have decoded how the brain signals intention and used that information to reanimate limbs which no longer function due to a spinal cord injury. By recording a monkey's brain activity while grasping a ball, scientists were able to create an algorithm that described how the monkey's arm responded to the brain's command. Then scientists reversibly paralyzed the monkey's arm and placed electrodes at specific points along the limb's muscle. When electricity was sent through the electrodes, following the dictates of the scientists' algorithm, the monkey grasped the ball despite being paralyzed. 

I wonder how this would play for motor apraxia.  If you can reanimate limbs, could you get better coordination and motor skills?

Neuromonics Clinical Summary Details Results of Effective Tinnitus Treatment

Here's a nice summary of the clinical trials for Neuronomics in peer reviewed journals.  


For sufferers of tinnitus, the condition described as ringing in the ears when no external sounds are present, treatment and relief have been elusive and inconsistent. Now, Neuromonics, Inc., has issued a comprehensive clinical summary of results to help tinnitus sufferers and providers understand that they can obtain effective treatment.

Neuromonics manufactures and distributes the only FDA-cleared, patented and clinically proven medical device designed for long-term significant relief of tinnitus. Clinically administered and monitored, the Neuromonics Tinnitus Treatment uses the non-invasive device, customized to each patient’s individual audiological profile, to deliver a neural stimulus that targets the brain’s auditory pathways.

The clinical summary (PDF), is available at Neuromonics’ website, or by requesting a copy by e-mailing rita.walbert@neuromonics.com. The summary includes detailed results of Neuromonics Tinnitus Treatment’s clinical efficacy as presented in papers appearing in peer-reviewed medical journals. In addition, the summary outlines nine additional studies that researchers have presented at medical meetings throughout the United States and Europe. Each provides additional evidence of clinical efficacy.

I Can't Find My Way Out of My Own Backyard

 I really don't have a good sense of direction although not quite as bad as the title of this post would have you believe.  Let's just say that before the GPS was invented that I got lost regularly on well known routes.  I use the GPS all the time... for all my doctor's visits.  Even the ones that I have been seeing for years.

With vision therapy, I have gotten alot better at finding my away around the Hospital of the University of Pennsylvania.  I used to get hugely lost in that insane labyrinth.  Honestly, someone needs to start doing master plans for hospitals.  It seems like they just build those things and then somebody with gazonga money comes along and donates a humongus wing.  The architects just slap the wing on with no regard to any sense of workflow, so you end up wandering around a maze.

Also, when I was in college, I went orienteering with a compass and a map.  I had a hard time learning how to read a topographic map, but eventually I got it.  However, I had a really hard time judging distance and understanding the relative size of hills in relationship to the size on the map.

Not good for the spatially challenged.   But vision therapy has helped alot.  Haven't tried orienteering since.

Let's just say that I assumed that the issue of finding my way around was assumed solved or manageable.

Then, I find that one day my GPS goes on the fritz on my way out to Lancaster. I have been out to Lancaster once a week gazillions of times.  You'd think I should know the way, hunh?   Well... No.
The GPS has crippled me.  I am so used to doing what I am told to do by the GPS that I've never looked at the landmarks around me.  So I got lost and was late.

Now, I am thinking that I really do need to tackle this problem.  There is a fancy name for this:  Topographic Agnosia, a visual agnosia in which a person cannot rely on visual cues to guide them directionally due to the inability to recognize objects. Nevertheless, they may still have an excellent capacity to describe the visual layout of the same place.  Patients with topographical agnosia have the ability to read maps, but become lost in familiar environments.


Comorbid conditions include: CAPD (Central Auditory Processing Disorder), Asperger's syndrome, prosopagnosia (an impairment in recognizing human faces), and nonverbal learning disabilities tend to co-occur with topographic agnosia, because they all affect closely related parts of the brain. In particular, the brain module that deals with faces is known to be located near the place module, so it would make sense that prosopagnosia commonly occurs with topographic agnosia. 

Developmentally, children are thought to develop landmark (or place) recognition.  That is they first learn to recognize familiar places.  The next skill acquired,  route knowledge, describes the information that encodes a sequential record of steps that lead from a starting point, through landmarks, and finally to a destination.

Descriptions of route learning also emphasize its grounding in an egocentric co-ordinate frame. It is assumed that a set of transformations take place by which the retinal position of an image is combined with information regarding the position of the eyes in the orbits and the position of the head upon the neck in order to represent the location of an object with reference to the body. This is termed egocentric (or body-centred) space and is the domain of spatial concepts such as left and right. Orientation is maintained within a learned route by representing egocentric position with respect to landmark (i.e. pass to the left of the grocery store, then turn right). A final, and crucial, aspect of route-knowledge is its presumed inflexibility. Because a route encodes only a series of linear instructions the representation is fragile, in that changes in crucial landmarks or detours render the learned path useless. 


Whereas route-learning is conducted within egocentric space, map-like representations are located within the domain of exocentric space, in which spatial relations between objects within the environment, including the observer, are emphasized (Taylor and Tversky, 1992). A developmental dissociation between egocentric and exocentric spatial representation has been demonstrated in a series of experiments by Acredolo indicating that these two co-ordinate frames are represented by adult subjects (Acredolo, 1977). In order to generate a representation of exocentric space, egocentric spatial decisions must be combined with an integrated measure of one's motion in the environment. While a tree may be to my right now, if I walk forward 10 paces and turn around, the tree will now be to my left. Though the egocentric position of the landmark has changed I am aware that the tree has not moved; the exocentric position has remained invariant. A representation of this invariance is available by combining the egocentric spatial judgements with a measure of the vector motion that was undertaken. 


Because of this representational co-ordinate frame, map-like representations are thought to preserve the Euclidean relationships between places in the environment. Thus, angle and distance relations between landmarks are readily available. In addition, maps are inherently flexible. This is a feature emphasized by O'Keefe and Nadel: `Whereas a route specifies a starting point, a goal, and a particular direction of movement from the former to the latter, a map specifies none of these, either in its construction or its usage. It can be used with equal facility to get from any particular place to any other. Additional flexibility derives from the freedom from specific objects and behaviours. If one path is blocked another can be easily found and followed.' (O'Keefe and Nadel, 1978, p. 87). 

So, how does this apply to me?
Until vision therapy kicked in, I focused on the back of the car in front of me.  I just didn't have the field of vision to notice what was around me.  I knew landmarks but I could pass them by because I just didn't know what was going on around me.   I can close my eyes and point to things correctly in a room.  I can tell you how to get to my doctors' offices.  I just can't drive there.

I'm more like the cab driver in Takahashi's study:

. . as he was driving his taxi in the same city [in which he had worked for 6 years], he suddenly lost his understanding of the route to his destination. As he could quickly recognize the buildings and landscapes around him, he was able to determine his current location. However, he could not determine in which direction he should proceed. He stopped taking passengers and tried to return to the main office, but didn't know the appropriate direction in which to drive. Using the surrounding buildings, scenery, and road signs he made several mistakes along the way. He remembered, during this time, passing the same places over and over again.

or, Patient MB:
`I was returning home when suddenly, even though I could recognize the places in which I was walking and the various shops and cafés on the street, I could not continue on my way because I no longer knew which way to go, whether to go forward or backward, or to turn to the right or to the left . .

I wonder if I have exocentric topographic agnosia.  I just patients can't  recall (or form) a link between directional information and landmark identity.  I just lose my heading.  Hmm... I wonder if this is a visual memory problem or a problem with time passage.  Another possibility is  that I am not able to maintain direction through  landmark, vestibular and idiothetic (self-motion) cues.

I wonder how much of this is related to lack of binocular vision.  If you can't see space, it kind of screws up your orientation to it.

My Body, My Self

In my chat with Dr. Siederman about getting 3D vision (binocular vision),  I  told him that I think I needed to get my posture straightened out.   It is well known throughout the vision community that lousy posture accentuates many visual problems such as strabismus.  Think about it. Your eyes need to sit in a stable properly aligned platform.

Your eyes are not aligned well so you start tilting your head and body in order to maintain a consistent visual image-- ie. avoiding seeing double etc.  Add in the fact that I don't have a good sense of balance, feet that point outwards. a "military" neck from arthritis (head jutting forwards) as well as a twist in my lower spine so I think I got a vicious circle going:  bad balance, poor body alignment, misaligned eyes all feeding on each other.

For a long time, I sat in a twisted S position with my one leg off to one side wrapped around the other leg, my hips opposed to my leg, my shoulder opposed to my hips, and my head opposed to my shoulder.  With all the balance work and vision therapy that I have done, I am sitting up without quite so much twisting.  However, I still sit with my hip to one side and my shoulders to another.

I am seeing a chiropractor to get better alignment but I have found that chiropractic adjustments, although they feel nice, don't last.  The chiropractor does have me work out twice a week to get better core muscles and flexibility in my shoulders and hips so I think that is something.  Hope I lose weight

So, Dr. Siederman recommended I go see an exercise physiologist, Maria Sykorova Pritz.  Maria left Czechoslovakia where she felt "buried alive" for more freedom here in the US.  However, she finds that many people here in the US are "prisoners of their bodies."  Maria disagrees with the emphasis in physical fitness to develop strength and endurance.


She feels:  Too many Americans are walking around with sculpted hardbodies that bristle with tension. They are prone to injury, stress and fatigue because their minds are divorced from their bodies and their body parts are disconnected from one another. Instead of acting in harmony and synchrony, the body is at war with itself.



When Maria walks down the street, she sees dead people - all these zombies and automatons, out of balance, out of alignment, out of sorts. Their bodies have become burdens, not instruments for appreciating the richness of life.


"People move too fast through life, not paying attention to the body," she says. "They are on automatic pilot, like on Interstate 95. When the body is connected, it's like taking the country roads. You move at your own speed. You experience movement and move more efficiently. The less muscular effort, the more you enhance your sensory skills."


She would turn the fitness pyramid upside down. To her, the essential principles, from most to least important, are balance, coordination, flexibility, endurance, quickness and strength. Too much muscle, she argues, interferes with the body's ability to move in the most natural, effortless way.

http://www.buildingbridgesmedia.com/whoweare/sykorova-pritz.php

Maria uses a holistic approach in her practice:  mind, body, emotions and spirituality.  She aims for
 "total body synchronisity"


We live through the heart," Maria says. "The brain is a backup - a computer that we fill with data."
She believes that the heart is the register of emotion, and that the body reveals "the anatomy of the spirit."

As I pulled into the driveway for Maria's office, I couldn't help but be struck by the statues on her front lawn and the wall around her house.  They were bronzed statues of children climbing a tree, standing on their hands or in motion.  I smiled. Maria seemed to be a woman after my own heart.  Her office was in a carriage house made of Pennsylvania quarry stone.  

I went upstairs and into her office which was full of sculptures and a wonderful painting of a woman aglow with swirling locks of hair.   I explained to her that I was referred to her by Dr. Seiderman's office because we would like to straighten out my posture in order to help me achieve better binocular vision.  I told her about my spinal twist and arthritic neck as well.   

She had me lay down on her massage table and started reading my body... just gently touching it and pausing.  Maria told me that I live too much in my head.  I agreed.  I told her I had Motor Apraxia as well.  She said that I am not using my sensory motor cortex enough and am using my medulla oblongata instead.

Then, Maria  had me relax and think of an X crossing my body with a bright white light filling my body up.  She also started to coach me gently to just "be".  Then, Maria started to move my right leg around in a circle and then my left.  When she finished set my feet down so that my soles of my feet were touching.   She also started to find trigger points in my legs.  Then she worked on my spine and back loosening them up.  While she was working on my spine, she told me that I was stuck in a flight or fright response.  Which makes sense given my sensory deficiencies.  If you can't trust your senses you would be a little hyper yourself.

She also really worked on my trigger points in my back and shoulders.  Then she started moving my arm in a circle while I traced my name in the air.  She also worked on the  trigger points in my neck.  She warned me that I might feel a bit achy for a few days. 

I think it really worked.  My shoulders were much looser and I think I started standing up straighter.

Here is a link to Maria's ebook on water therapy.

Dinner With Doctor Seiderman

Dr Seiderman had me and another middle aged patient present our cases at a dinner with his staff.  We both have similar problems with a lack of depth perception.   I am quite honored to be worthy of the attention as Dr. Seiderman is one of the pioneers of vision therapy.

I told the tale that my Gentle Readers know so well.  Getting lost on the way to Dr. Herzberg and driving over the bridge to New Jersey instead of circling around the Pennsylvania Turnpike.   Being late because I've dropped something out of the refrigerator and had to clean it up.  Problems with mashing up Powerpoint presentations and formulas in Excel spreadsheets. Not being able to put on jewelry or tweeze my facial hair very easily before I took vision therapy.  I had held jobs in my younger days that were just insane for me to have.  Waitressing requires a lot of spatial awarenesss and hand eye coordination.  Being a secretary involves a lot of eye tracking as you move from written draft to typewriter (yes, I am that old) or proofreading.  I did some econometric forecasting which involved printouts with rows and rows of numbers.  Also, just how exhausting living a life with so many physical problems can be.  When I was working, I would come home and fall asleep around 8 pm on the couch.  My husband would poke my lifeless carcass around 10 pm and convince me to haul it up the stairs and into bed.  My problems are genetic as I remember my parents doing the same thing.

"L", the other patient, was a dental hygientist who taught at University of Pennsylvania Dental School.  One of her patients happened to be Dr. Seiderman.  Apparently, Dr. Seiderman spent a fair amount of time looking up into her eyes as she cleaned his teeth and being an optometrist knew what well-aligned eyes were supposed to look like.  He told her something was not quite right and got her to come in and see him.  Poor "L" had gotten a lot more pooped out than me, to the point that she had gotten Chronic Fatigue Syndrome and had spent a year in bed totally wiped out. 

"L" also has problems processing auditory information.  She says that she always seems to have an internal dialog going on inside her head and is juggling processing that dialog at the same time she is trying to hear what is going on. 

The vision therapists were already impressed by both of ours work ethic.  Both of us approach our therapy and try extremely hard.   I work till I want to knock my socks off.   But  I can understand why "L" would work as hard as I do.  Since up until recently, everything was so darn hard and to get to where everyone else is, you had to work flat out or there would be dire consequences, you got in the habit of trying really, really hard.  They find both of us to be perfectionists... but they don't realize that in order to approach the level of functioning at an average level we have to try to be perfect.  If we didn't try to be perfect and use what strengths we have, we would have been really thrown in the dust bin.   So when you are in the habit of trying hard to make up for your weakness, when you do what comes naturally to you and apply that work ethic you can really succeed at some things.

Dr Seiderman wants "L" and I to really start working on activities in space.  He points out the difference between some of the top athletes that have come to see him and us.  These athletes are very aware of their bodies and their relationship to the world around them.  "L" and I are not so connected to space.  We are starting to step into the world but we haven't connected to it yet. 

Dr Seiderman is going to be writing a book called "Overlooked", about our generation who had never gotten diagnosed.  I think he is quite right to raise awareness.  These problems that "L" and I suffer from are genetic ones.  So much is going into screening children and no red flags are being raised for adults.  Adults don't know that many of the problems that they may be suffering from are vision/auditory/motor skill problems.  Instead, my generation walks into a family doctor's office with physical complaints of fatigue or high blood pressure or into a psychologists office with complaints of stress, anxiety or depression.  These doctors are ill-equipped to spot "learning disabilities" in adults and are not getting to the route cause of the problems.

The Mathematics of Happiness?

Earlier in my life in the course of getting a bachelor's degree in economics,  I counted up happiness both the happiness we get as individuals and the happiness we get as a society.    Economics measures happiness in imaginary units known as utils.  The idea being that for a given utility curve (set of tradeoffs) you are equally happy.  You can jump to higher or lower utility curve (ie getting more or less happy). 
However, In Emotional Equations, Conley takes the mathematics of human happiness a step further, creating simple formulas like anxiety = uncertainty x powerlessness, which, when used systematically, he says, can give individuals and organizations a concrete method for addressing the human needs that drive them.

Who'd of thunk that we could systematize our emotions so... If our emotions can be systematized, than they can be digitized.  I wonder if this is our first step towards emotional robots.

Update on Hubby's Journey Through His Cortex

manga hubby

Hubby has been voyaging through his neurons as well.   He got himself checked out and is suffering from Auditory Processing Disorder, Convergence Insufficiency, and deficits with Bilateral Motor Skills, Balance, Working Memory and Processing Speed.   

Hubby had a chat with Wilma, an Occupational Therapist,  who looked at his total profile and told him that he would have to start factoring in rest as in taking a nap periodically through the day.  Wilma's husband had chronic kidney disease so she knows what she is talking about.   It is really necessary for hubby to rest between meetings and not just charge through the day.  Unfortunately, work often just goes from one teleconference to another straight through.  Hubby just has to plan out those breaks.

Hubby has started up with our peeps at A Total Approach.  He has the same Anne peep that I have had.  Hubby is working on balametrics and tomatis; tossing bean bags while walking on a balance beam and batting a ball suspended on a string.   He is not jumping on a balance beam like the gymnast in the picture!  Also, his balance beam is only a few inches off the floor.   He is wearing headphones that play specially altered music.  I  think Hubby is starting his therapy off at a much higher level than me.   He is already batting the ball on a string with his hands.

Hubby gets a massage from Anne every day.  I am quite jealous.  I didn't get one.  I have joking with Anne that she just wants to get her mitts on my hubby!   This massage is actually more of a petting or brushing than a Swedish massage.   She strokes Hubby's arms and the outside sides of his legs and the sides of his chest.  Also, she makes a figure eight on his back.  

Finally, hubby is working on a 500 piece puzzle for his final half hour.   Next week,  he will be playing Labyrinth with Anne.  Anne does not play Labyrinth well so hubby will be showing her the winning strategies that he showed me.

Hubby, like me, does get quite tired from this and is napping a lot.  Well, one more week to go and he will finish his first round of PT.  Then he gets a break for a month.

Already, Hubby is starting to hear better and see things more clearly.   He can hear more notes in a song and they seem more crisper. 

He feels more connected to his body.  One of the concerns we've had is that Hubby is a bit of a brain living in his cranium without being connected to his body.  He is enjoying being back in his body.

Hubby is enjoying his time with A Total Approach.  We are now calling them our "peeps".  They have truly been a very loving bunch of folks to both of us.

You Are Not Your Brain

When I have been thinking about the root of my problems, unfortunately, I haven't been able to find any Grand Theory of Me.  I do think some of these things relates to a larger question of consciousness and cognition.  Obviously, with my problems, my perceptions, awareness and consciousness is a bit different than other peoples.   Some of this has meant that I don't see or hear what is obvious to others and some of it has meant that I think about the world in different ways.  Witness This Blog!!!

Also, it has meant that I have my own set of strengths that have either been innate or have been honed by the way I get inputs from the sensory world.  Witness This Blog!!!

And this thought of  what is innate within me and what has been formed leads to some interesting questions.  As I have fixed a number of deficits, my awareness and consciousness has changed.  I have written a lot about the new sights I have seen as a result of vision therapy and the new sounds that I have heard in music as a result of auditory therapy, etc.

 However, what is interesting is that I have had a visual world and a certain amount of visual cognition, despite a diagnosis of non-verbal learning disorder (living in text world) and convergence insufficiency/intermittant divergent strabismus, long before my vision improved.  Same for auditory, despite a diagnosis of auditory processing disorder.  For many years, I had been unusually sensitive to music.

On the other hand, how much do I suffer from a disordered cognition that a globalized condition such as non-verbal learning disorder indicates?  It doesn't help that NLD is a spectrum disorder and that it manifests itself differently in different ways for each individual.

So the following article on the origins of consciousness really speaks to me.  How much of my consciousness is as a result of certain hardwired aspects of my brain and how much are intuitions that structure my experience.

Contemporary research on consciousness in neuroscience rests on unquestioned but highly questionable foundations. Human nature is no less mysterious now than it was a hundred years ago," writes philosopher Alva Noë in his book Out of Our Heads.

It's a bold assertion in an age when fMRI has enabled us to see images of the brain functioning in real time, and when a majority of prominent public intellectuals (Stephen Hawking, Eric Kandel) have argued either implicitly or vociferously in favor of reductionism. The "brain-as-calculating machine" analogy assumes that human thought, personality, memory, and emotion are located somewhere in the gray matter protected by the skull. In other words, you -- at least, the waking you who gets out of bed in the morning -- are your brain.

...
What Noë is advocating is an entirely new approach -- what if we were to try expand our conception of consciousness by crossing that boundary out of the skull, to encompass "not just our bodies and our movements over time, but also the dynamic interactions that we have with the larger world around us, including the social world?"

Begin by looking at our connections, he says, and we'll find the tools for gaining insight into the nature of consciousness. In fact, lots of information that stimulates our nervous system doesn't get experienced by us. For example: "I might spend an hour talking to you and not notice what color your shirt is. In some sense I saw your shirt. It was there before me and it activated my nervous system and yet I might be unable in any way to make use of that information." It's an interesting puzzle: intuition structures our experience in a way that can't be traced back to the nervous system.

My vision is getting better and better: More awareness of space

Eye movements abductors
Eye movements abductors (Photo credit: Wikipedia)
Between the prisms, vision therapy, Cellfield and RevitalVision, I am seeing more space.

The prisms are moving my eyes closer together.  I can do about 30 diopters on one measure and 18 diopters on another measure.  Sorry for the vision therapy junkies but I forget which is base in and which is base out.  I have intermittant divergent strabismus so my problem is getting my eyes to converge properly. 

My left eye is waking up and staying on as  a result of RevitalVision.  RevitalVision involves looking at Gabor patches in an effort to improve contrast sensitivity.  Sometimes amblyopia results when the lazy eye does not see the world with the same contrast as the better eye or because the lazy eye needs a much stronger prescription than the better eye. .  Sometimes, amblyopia results because of misalignment of the eye. Whatever the cause of my left eye shutting down,  I am definitely seeing a lot more detail in the world and a lot more space between objects and a lot more dimensionality in the world.  It stands to reason if you have a lot more clarity you can see a lot more definition between objects and so they pop out more.

What Will This Day Be Like, I Wonder...

What Will My Future Be?

I went back to the career counselor and am taking a number of assessments. 

The First is the Meyers Briggs.  I am an ENTP:  Extravert, Intuitive, Thinking, Perceiving.  Very heavy on the Intuitive and a bit on the Extravert side.  Very slight on the Thinking and Perceiving side.  ENTPs are your born entrepreneurs and creative types. Law and Finance also come up as career choices.

I have also done a skills interest assessment with the top careers being public administrator, lawyer, and elected official.  Other possibilities include arts management and photographer.  Well, given the current political scene which has me rather turned off, I don't see myself running for political office!  Sorry, the next President of the United States is not blogging here!  Just in case, you had any doubts! 

I don't see being a photographer.  I can't hold a camera steady so my pictures always come out a bit fuzzy. 

I don't see finance as being a career choice.   Too many spreadsheets with too much eye tracking.

At first, I thought being a lawyer was out as I have auditory processing disorder but, Maxine, my audiologist, said that she has lots of attorneys with APD and they all manage.

But, given today's job market and the expense of law school,  a career as a lawyer gives me a bit of pause.  However, maybe I am cut out for something in the legal/public policy side.  Whether or not, that involves getting a JD is another story.

RevitalVision is really helping

I have been doing RevitalVision almost every day.  It is a little hard to do it daily because it makes you wait 20 hours between sessions.   So if I don't do it exactly at the same time, it is easy to skip a day.

Also, it has been hard to do it at night because I get bored and fall asleep in the middle of it.  But it is helping with my contrast sensitivity.  It is also helping with 3D vision as my left eye is not shutting down.

Contrast Sensitivity and Auditory Discrimination

Illustration for function of contrast sensitiv...
Illustration for function of contrast sensitivity. Русский: Иллюстрация к статье функция контрастной чувствительности. (Photo credit: Wikipedia)
Went to visit my audiologist, Maxine Young,  to update her as to how I am doing.   I told her about my work with RevitalVision and how it is working on contrast sensitivity with my left eye.  Just for grins and giggles, I have been smelling some scents at the same time as I am doing RevitalVision in an effort to wake up my sense of smell.  There is no scientific studies on this.  I am just using my gut !

I was wondering if she had anything similar up her sleeve in the way of increasing auditory contrast.  I still do not always hear consonants correctly.  She has a program called LACE that helps people improve auditory discrimination (which is the auditory counterpart to contrast sensitivity) so I will try that.  One thing she noted is that if you improve contrast with one sense that contrast with other senses improves as well.    I agree with her in that I tend to see a lot of improvement when I do multimodal therapy. 

We also talked about memory.  I told her that my PTs and OTs think I have a memory program as well. She is going to have another neuropsychologist evaluate me again for Cogmed
