The brains of autistic individuals experience widespread molecular changes across the cerebral cortex. The most differential changes occur in the primary visual cortex, according to a recent study published in Nature that analyzed 11 cortical areas of the brain.1 Most molecular profiling studies highlight changes limited to the frontal and temporal cortex.
“It is interesting to speculate that the substantial changes observed in primary sensory regions may relate to the widespread sensory processing differences in ASD, which are so pervasive that they have been included in the DSM-5 diagnostic criteria,” the researchers wrote.
