Evolution of the Neocortex

Xiao Huang: DOORM, what changes occurred in the neocortex of primates during evolution?

DOORM: During evolution, the neocortex of primates developed complex folds on its surface, accompanied by deep ridges, grooves, and fissures, which increased the surface area of the cortex. These changes made the neocortex the main part of the human brain, accounting for 80% of its weight. The complexity of these folds and structures provides primates with greater cognitive abilities and the capacity to process complex information.
