- somatosensory cortex
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.
includes the caudate nucleus and the putamen; part of the basal ganglia. Implicated in habit learning.
- subgenual area 25
also known as area 25 of Brodmann-1905; a subdivision of the cingulate region
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
a group of cells in the midbrain that use dopamine, and connect to the striatum
- subventricular zone
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.
a cleft or fissure in the cerebrum (compare gyrus)
- superior parietal cortex
a region in the upper part of the parietal lobe.
- superior temporal gyrus
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
a sulcus in the upper part of the temporal lobe.
- supplementary motor area
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.
