Learned associations between effects of abused drugs and the drug administration environment are important in drug addiction. Histochemical and electrophysiological studies suggest that these associations are encoded in sparsely distributed nucleus accumbens neurons that are selectively activated by drugs and drug-associated cues. Although correlations have(More)
Repeated cocaine administration to rats outside their home cage induces behavioral sensitization that is strongly modulated by the drug administration environment. We hypothesized that stimuli in the drug administration environment activate specific sets of striatal neurons, called neuronal ensembles, for further cocaine-enhanced activation, and that(More)
