What does the postcentral sulcus do?
The postcentral sulcus is a sulcus of the parietal lobe that separates the postcentral gyrus from the remainder of the parietal lobe, thus dividing the primary somatosensory cortex from the secondary somatosensory cortex. It runs parallel and posterior to the central sulcus.
What is the function of the postcentral gyrus in the brain?
The postcentral gyrus is a prominent gyrus in the lateral parietal lobe of the human brain. It is the location of the primary somatosensory cortex, the main sensory receptive area for the sense of touch….

What does precentral sulcus do?
An important functional area of the frontal lobe is the precentral gyrus, which is located rostral to the central sulcus. The precentral gyrus is called the somato-motor cortex because it controls volitional movements of the contralateral side of the body.
What does the intraparietal sulcus do?
Different subregions or areas of the intraparietal sulcus are involved in the planning of eye movements, grasping movements, reaching, and defensive forelimb and head movements. Sensory guidance is based on somatosensory, visual, and, to a lesser extent, auditory inputs.
What is the function of the sulcus?
A sulcus (plural: sulci) is another name for a groove in the cerebral cortex. Each gyrus is surrounded by sulci and together, the gyri and sulci help to increase the surface area of the cerebral cortex and form brain divisions.
What best describes the Broca’s area?
What best describes the Broca’s area? Broca’s area is a premotor area for speech sounds.
What does a gyrus do?
Each gyrus is surrounded by sulci and together, the gyri and sulci help to increase the surface area of the cerebral cortex and form brain divisions. They form brain divisions by creating boundaries between the lobes, so these are easily identifiable, as well as serving to divide the brain into two hemispheres.
What supplies blood to the precentral gyrus?
B, The lower two-thirds of the central lobe is predominantly supplied by the central artery. On the superior third, the precentral gyrus is supplied by the posterior interior frontal artery and the postcentral gyrus by the superior parietal artery.
What does Intraparietal mean?
Definition of intraparietal 1 : intramural sense 2. 2 : located within the parietal lobe of the cerebrum.
What is IPL in the brain?
Abstract. The inferior parietal lobe (IPL) is a key neural substrate underlying diverse mental processes, from basic attention to language and social cognition, that define human interactions. Its putative domain-global role appears to tie into poorly understood differences between cognitive domains in both hemispheres …
What happens if the sulcus is damaged?
Perisylvian syndrome is a rare neurological disease which results from damage to the lateral sulcus (or Sylvian sulcus), resulting in language and speech problems. Finally, abnormalities of the superior temporal gyrus have been associated with some of the symptoms of schizophrenia (Barta et al., 1990).
