|
Striatum (Putamen) |
Receives input from cerebral cortex and outputs onto basal ganglia |
|
|
globus pallidus |
part of basal ganglia, regulates voluntary movement |
|
|
Subthalamic nucleus |
component of basal ganglia control system that performs action selection |
|
|
substantia nigra pars compacta |
dopaminergic neuron body that governs reward-based learning. In midbrain |
|
|
substantia nigra pars reticulata |
output nucleus of the basal ganglia to motor thalamus. |
|
|
direct pathway |
neuronal circuit passing through the basal ganglia which causes excitation of movements
|
|
|
indirect pathway |
neuronal circuit passing through basal ganglia which inhibits motor movement |
|
|
dopamine D1 and D2 receptors |
two types of dopamine receptors. D1 found on direct pathway, have an excitation effect. D2 found on indirect pathway, have inhibitory effect. This tips the balance towards more action. |
|
|
medium spiny neuron |
inhibitory neurons of the basal ganglia, form dendrite trees which receive inputs from outside striatum. |
