Only one human brain module (corresponding to genes expressed in the cortex) was not preserved in chimpanzee brains.
It took more than five years of painstaking probing, as Miller recorded from cells in the monkey brain, but he was eventually able to show that the prefrontal cortex wasn't simply an aggregator of information.
Interestingly, connections from other brain regions to the prefrontal cortex are not fully developed until the early 20s.
His MRI research showing that connections from other brain regions to the prefrontal cortex are not fully developed until the early 20s was cited in a recent Supreme Court argument as neurobiological basis for ruling out the death penalty and life sentences for young people committing murder.
However, occipitotemporal cortex is not the only brain region that has been implicated in object-category learning.
Visual cortex is not the only brain area revealing overlap between the activation associated with imagery and perception; rather, the areas activated depend on the type of imagery involved.
"The frontal cortex is designed to inhibit the fear response system in the amygdala, but we can show in some of the recent imaging studies that the frontal cortex is not activating normally in some traumatized brains," he says.
The IT cortex is not homing in on one particular person at all; that transformation must happen at a point even deeper in the brain.
"As these brain functions are getting parceled out, the visual cortex isn't getting its typical function, which is to do vision.
Histological assessment of the brain structure revealed some minor pathological changes, but the number of brain cortex cells was not affected.
