abstract：:Mechanisms by which opiates alter neuronal functions, including neuroendocrine functions, are not well defined. We have previously demonstrated that morphine rapidly and transiently increases expression of the proto-oncogene c-fos in the rat caudate-putamen. This regulation of the c-fos gene by morphine may represent ...
