gyri
Cerebral surface folds
Gyri is the plural of gyrus, a ridge on the surface of the brain.
The brain's characteristic wrinkled appearance comes from these raised folds separated by grooves called sulci.
The surgeon carefully navigated between the gyri.
The singular gyrus appears in anatomical names for specific brain regions.
