Area S2 is involved with specific touch perception and is thus integrally linked with the amygdala and hippocampus to encode and reinforce memories. Parietal ventral area is the somatosensory relay to the premotor cortex and somatosensory memory hub, BA5. BA5 is the topographically organized somato memory field and association area.
The motor cortex is the region of the cerebral cortex involved in the planning, control, and execution of voluntary movements. The motor cortex is an area of the frontal lobe located in the posterior precentral gyrus immediately anterior to the central sulcus. Motor cortex controls different muscle groups
Somatosensory & Motor Research is a peer-reviewed medical journal that covers all topics relating to the neural bases for somatic sensation, somatic motor function, somatic motor integration, and modeling thereof. [1] The journal has been published quarterly by Informa since 1983.
The general (spinal) somatic efferent neurons (GSE, somatomotor, or somatic motor fibers) arise from motor neuron cell bodies in the ventral horns of the gray matter within the spinal cord. They exit the spinal cord through the ventral roots , carrying motor impulses to skeletal muscle through a neuromuscular junction .
The sensory cortex can refer sometimes to the primary somatosensory cortex, or it can be used as a term for the primary and secondary cortices of the different senses (two cortices each, on left and right hemisphere): the visual cortex on the occipital lobes, the auditory cortex on the temporal lobes, the primary olfactory cortex on the uncus of the piriform region of the temporal lobes, the ...
An area at the entrance to the lateral sulcus, adjoining the primary somatosensory cortex (S1), is called the parietal ventral (PV) area. Posterior to PV is the secondary somatosensory area (area S2, which must not be confused with "region S2" which designates the entire secondary somatosensory cortex, of which area S2 is a part).
Brodmann area 7 is part of the parietal cortex in the human brain. Situated posterior to the primary somatosensory cortex ( Brodmann areas 3, 1 and 2 ), and superior to the occipital lobe , this region is believed to play a role in visuo-motor coordination (e.g., in reaching to grasp an object).
In neuroanatomy, the primary somatosensory cortex is located in the postcentral gyrus of the brain's parietal lobe, and is part of the somatosensory system.It was initially defined from surface stimulation studies of Wilder Penfield, and parallel surface potential studies of Bard, Woolsey, and Marshall.
