Sulci and gyri brain
WebGyrification is the process whereby folding patterns of sulci and gyri develop on the surface of the brain. Several of these patterns are asymmetrical between the right and left side of the cerebral hemispheres, and several distinguish the human brain from that of other species. The gyrus is a ridge of cerebral cortex, whereas the sulcus is a ...
