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.

The grooves may actually bring those areas closer together in space, shortening the connections between them and speeding communications. The implication, the researchers say, is that variability in ...

“While sulci can change over development, getting deeper or shallower and developing thinner or thicker gray matter — probably in ways that depend on experience — our particular configuration of sulci ...

The reason our brains have that wrinkly, walnut shape may be that the rapid growth of the brain's outer brain — the gray matter — is constrained by the white matter, a new study shows.
