D1 go and D2 no-go units
except at its most anterior pole, the striatum is divided into the caudate nucleus and putamen by the internal capsule
consists of two separate compartments (ks4, 856)
matrix
striosome (aka patches)
the D1 and D2 receptors in the putamen get their input from the substantia nigra pars compacta
main input gateway for the basal ganglia
not much spontaneous activity
dopamine loss disrupts initiation and execution of feeding and related behaviors
is this specific to striatum???
