, Medium spinystriatalneurons makeup about 95% of the striatal neuron population.
They receive a number of inputs, in addition to the important cortical input, including:
excitatory glutamatergic inputs from the thalamus;
cholinergic input from striatal interneurons
gamma-aminobutyric acid (GABA), substance P, and encephalin input from
adjacent medium spiny striatal neurons
GABA input from small interneurons
-a large input from dopamine-containing neurons in the substantia nigra pars
compacta (SNpc)
