Is it true or false that the deep grooves within the cerebral hemispheres are known as gyri?
False! deep grooves are called fissures!
Deep grooves in the brain a sign of intelligence?
The deep grooves are called sulci(sing. sulcus) while raised portions are called gyri(which are bulged portions between two adjacent sulci). The number of gyri determines the intelligence of a person, as more the convolutions, more will be the surface area of the cortex.
What is the difference between gyri and sulci?
Parts of the Brain: Cerebrum-largest part of brain, 7/8 total mass of the brain. * 2 cerebral hemispheres: # ridges- gyri # grooves- sulci *Gyrus(gyri)-is a ridge on the cerebral cortex. Folds on the brain material. Many ridgescalled convolutions, or gyri, or gyrus, separated by grooves, mark the cerebrum's surface. *Sulcus(sulci)-shallow grooves on the brain. Generally, a shallow to somewhat deep groove is called a sulcus, or sulci, and a very deep groove is called a fissure.
