The Sulcus is a shallow furrow on the surface of the brain separating convolutions.
Sulci.
The elevations are called Gyri.
Each of sulci and gyri have their own names.
Actually, they are called sulci.
Sulci (singular sulcus) are the folds of the cerebral cortex.
The ridges and furrows in the cerebral cortex are actually folds. The 'furrows' are called sulci and the 'bumps' are called gyri.
Gyri are the folds in the brain that store memories. These are located on the cerebral cortex, along with the sulci.
Gyri is the name of the folds in the gray matter of the brain that form the cerebral cortex. These folds increase the surface area of the cortex, facilitating diffusion of nutrients, respiratory gases, and wastes between the nervous tissue and the cerebrospinal fluid and blood stream.
Gyri are the folds in the brain that store memories. These are located on the cerebral cortex, along with the sulci.
The fissures or the sulci are the inward folds of cerebral tissue.
The inward folds of cerebral tissue are called fissures or sulci. The sulci is surrounded by other depressions or grooves known as gyri.
The inward folds of cerebral tissue are called sulci. These are narrow fissures that separate adjacent convolutions of the brain.
== == In short, the cerebral cortex is the outer and largest part of the brain, that covers its smaller parts and is usually easily visible on brain illustrations. It contains gray matter (neurons) responsible for the "higher" functions of thinking and information processing. There's also a lot of information about the cerebral cortex on http://www.answers.com/cerebral+cortex
The inward folds of cerebral tissue are called fissures or sulci. The sulci is surrounded by other depressions or grooves known as gyri.
The folds of the brain cortex increase the surface area. Because the processing of the brain is done in the cortex, having an increased surface area allows for more processing power.
