Inputs from nearly every part of the cortical mantle make connections in the striatum. WebMore recent interest in the striatum has also focused on the actions of opiates and endogenous opiate peptides (enkephalins). Indeed the striatum contains significant amounts of enkephalin and an enkephalin-containing striatopallidal fiber system has been described ( Cuello & Paxinos, 1978 ). Moreover, the highest degree of opiate receptor ... gce warrington
