Webb8 aug. 2012 · In the orbitofrontal cortex, this procedure resulted in a cluster that extended into the anterior insula; to restrict the ROI to the prefrontal cortex, we thus multiplied the functional mask with an anatomical mask based on the frontal pole and orbitofrontal cortex regions defined by the Harvard–Oxford cortical structural atlas implemented in … WebbAllocortex. The allocortex or heterogenetic cortex, and neocortex are the two types of cerebral cortex in the brain. The allocortex is the much smaller area of cortex taking up just 10%; the neocortex takes up the remaining 90%. [1] It is characterized by having just three or four cortical layers, in contrast with the six layers of the neocortex.
