HYP - High yield points: Basal nuclei

HYP - High yield points:
Basal nuclei
ü A group of nuclei deep within the cerebral white matter
ü Caudate nucleus – arches over the thalamus
ü Lentiform nucleus – “lens shaped”
ü Amygdala – sits on top of the caudate nucleus
o Functionally belongs with the limbic system
ü Lentiform nucleus
ü Divided into two parts
o Globus pallidus
o Putamen
Basal nuclei – functions:
ü Cooperate with the cerebral cortex in controlling movements
ü Receive input from many cortical areas
ü Evidence shows that they:
ü Start, stop, and regulate intensity of voluntary movements & estimate the passage of time
