NeuronCompartmentPropertyConnectivityNotes
Neostriatum interneuron ACh cellAxon terminalGlutamate.The mGluRs belonging to group I and II are located on the axon terminals of striatal cholinergic interneurons, their activation resulting in facilitation and inhibition, respectively, of acetylcholine release (Marti M et al, 20011 ).
