somatosensory cortex search for term

or primary somesthetic area / primary somatic sensory area. It is located in the parietal lobe, and deals with information from the various "touch" receptors, such as temperature, pressure, limb position, movement, pain, etc. It has been implicated in the processes by which memories (or some type of them) are consolidated during sleep.

striatum search for term

includes the caudate nucleus and the putamen; part of the basal ganglia. Implicated in habit learning.

subgenual area 25 search for term

also known as area 25 of Brodmann-1905; a subdivision of the cingulate region

subiculum search for term

a substructure of the hippocampus, active during the retrieval of newly-learned face-name associations (but less so as retrieval became more practiced). (also see dentate gyrus and cornu ammonis)

substantia nigra search for term

a group of cells in the midbrain that use dopamine, and connect to the striatum

subventricular zone search for term

is located in the walls of the lateral ventricle. It is one of two regions in the adult brain in which new brain cells are created. New neurons created in this region travel to the olfactory bulb.

sulcus search for term

a cleft or fissure in the cerebrum (compare gyrus)

superior parietal cortex search for term

a region in the upper part of the parietal lobe.

superior temporal gyrus search for term

a gyrus in the upper part of the temporal lobe. Contains the primary auditory cortex. The anterior part of this region has been implicated in generating the aha! experience of insight.

superior temporal sulcus search for term

a sulcus in the upper part of the temporal lobe.

supplementary motor area search for term

is part of the motor cortex, found in the medial frontal lobe. The other parts are the primary motor cortex and the premotor cortex. Like the presupplementary motor area, it receives input from the basal ganglia and cerebellum. It has been implicated in the initiation and control of voluntary movements.
