Smaller, shallow brain folds in the posteromedial cortex show greater thinning with age and Alzheimer’s disease, and their ...

Historically, there have been three broad ideas about how gyri and sulci develop. One idea is that some areas of the cortex simply grow more and rise above other areas, creating the gyri.

Anyone who has seen pictures or models of the human brain is aware that the outside layer, or cortex, of the brain is folded in an intricate pattern of “hills”, called gyri, and “valleys ...
