The striatal striosome compartment is considered one of the critical stations related to obsessive compulsive disorder. Medium spiny projection neurons in the striosomes but not in the matrix have mu-opioid receptors whose physiological roles have not fully examined. We found that prior blockade of muscarinic receptors augmented the suppressive effect of the mu-opioid receptor agonist DAMGO on the inhibitory postsynaptic currents. This phenomenon suggests the notion that the cessation of tonic action potential discharges of cholinergic interneurons in the striatum(the pause response of the tonically active cholinergic neurons of the striatum) during behavioral learning induces disinhibition of neuronal activities of the striosomal medium spiny neurons which are believed to encode motivational information.
