The central sulcus is a deep groove (or furrow) in the brain that separates the frontal and parietal lobes of the cerebrum. The frontal lobe is known as the motor cotrex and the parietal lobe is known as the sensory cortex. the central sulcus has a 'map' of the human body on each side that corresponds to the other side. So when the sensory part is stimulated, its associated motor part is right across the sulcus. The model of the human body in relation to how many nerves are associated with each body part is called a homonculus and you can see one in one of the links below:

What are the folds in the cerebral cortex called?

The folds in the cerebral cortex are called sulci (singular: sulcus) and gyri (singular: gyrus). Sulci are the grooves or furrows, while gyri are the ridges or bumps on the brain's surface. These folds increase the surface area of the brain, allowing for more neurons to be packed within the limited space of the skull.


What is the name given to the valleys on the surface of the cerebral cortex?

The name given to the valleys on the surface of the cerebral cortex is "sulci," while the raised ridges are called "gyri." These folds increase the surface area of the brain, allowing for more neurons and synapses to fit within the skull.


What is the function of folds in a mammalian brain?

They are called sulci (plural of sulcus).


Is it true or false that the deep grooves within the cerebral hemispheres are known as gyri?

False. The deep grooves within the cerebral hemispheres are known as sulci, while the raised folds are called gyri.


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.

What are 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.


What are the inwards folds of cerebral tissue?

The inward folds of cerebral tissue are known as sulci. They are grooves or furrows that separate the gyri, which are the raised folds of the cerebral cortex. Sulci increase the surface area of the brain, allowing for more complex functions to be carried out.
