Document Summary
What are the basal ganglia: basal located in the basal part of the forebrain/telencephalon, ganglia definition: cluster of neurons in the peripheral nervous system. Where are the basal ganglia: cerebral cortex (gray matter) Superficial cortical layer of gray matter containing neuronal cell bodies: cerebral white matter. Deeper layer of white matter containing fibers connecting cell bodies to other cortical areas and the rest of the brain. Basal ganglia deepest layer of large collections of neuronal cell bodies. Why are the basal ganglia important: voluntary movement control. Coordination speed and strength of movements: procedural learning of routines/habits, cognition, emotions, estimation of time. Striatum is divided into: caudate nucleus, putamen and nucleus accumbens. Pallidium is divided into: globus pallidus. Internal (gpi) and external (gpe: ventral pallidum. Lentiform nucleus: globus pallidus and putamen. Corpus striatum: stiatum and globus pallidus. Anatomical defintion: claustrum, amygdala, striatum and pallidum. Clinical definition: substantia nigra (sn) (mesencephalon)
