The foreshortening of the central sulcus has been found to be an abnormality associated with this syndrome. [14] This can be seen with the abnormal dorsal end of the central sulcus in individuals with Williams syndrome. [14] However, the abnormal dorsal end of the central sulcus has not been found to be linked to impaired general intelligence. [14]
The borders of this area are: the precentral sulcus in front , the medial longitudinal fissure at the top , the central sulcus in back (posteriorly), and the lateral sulcus along the bottom . This area of cortex, as shown by Wilder Penfield and others, has the pattern of a homunculus. That is, the legs and trunk fold over the midline; the arms ...
The insular cortex is divided by the central sulcus of the insula, into two parts: the anterior insula and the posterior insula in which more than a dozen field areas have been identified. The cortical area overlying the insula toward the lateral surface of the brain is the operculum (meaning lid). The opercula are formed from parts of the ...
This region is extremely rich in serotonin transporters and is considered as a governor for a vast network involving areas like hypothalamus and brain stem, which influences changes in appetite and sleep; the amygdala and insula, which affect the mood and anxiety; the hippocampus, which plays an important role in memory formation; and some parts of the frontal cortex responsible for self ...
The parietal lobe is positioned above the occipital lobe and behind the frontal lobe and central sulcus.. The parietal lobe integrates sensory information among various modalities, including spatial sense and navigation (proprioception), the main sensory receptive area for the sense of touch (mechanoreception) in the somatosensory cortex which is just posterior to the central sulcus in the ...
The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain.The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear, as it is critical in the regulation of amygdala activity in humans.

CeA is responsible for "autonomic components of emotions (e.g., changes in heart rate, blood pressure, and respiration) primarily through output pathways to the lateral hypothalamus and brain stem." The CeA is also responsible for "conscious perception of emotion primarily through the ventral amygdalofugal output pathway to the anterior ...
The brain is the central organ of the human nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum , the brainstem and the cerebellum . The brain controls most of the activities of the body , processing, integrating, and coordinating the information it receives from the sensory nervous system .
