Plasticity of dendritic spines, which are mostly excitatory glutamatergic synapses, plays important roles in learning and memory. Addiction is believed to be a pathological form of learning. Our studies reveal that MORs modulate the stability of dendritic spines. We are focusing on the molecular and cellular mechanism underlying opioid addiction, particularly opioid-induced changes in the morphology and function of dendritic spines.
