Endocannabinoids (eCBs) regulate neuronal activity in the dorso-lateral striatum (DLS), a brain region that is involved in habitual behaviors. How synaptic eCB signaling contributes to habitual behaviors under physiological and pathological conditions remains unclear. Using a mouse model of cannabinoid tolerance, we found that persistent activation of the eCB pathway impaired eCB-mediated...
