The following article is on how natural odors and sounds interact as mothers' cortexes develop to facilitate efficient detection of distress in their pups.
The olfactory-auditory integration appeared in lactating mothers shortly after they had given birth and had a particularly strong effect on the detection of pup distress calls.
Taken together, the findings suggest that motherhood is associated with a previously un-described form of multisensory processing in the auditory cortex.
“We have shown that motherhood is associated with a rapid and robust appearance of olfactory-auditory integration in the primary auditory cortex occurring along with stimulus-specific adaptation to pup distress calls,” says Prof. Mizrahi. “These processes help to explain how changes in neocortical networks facilitate efficient detection of pups by their caring mothers.”
