Differential neuroendocrine and behavioral responses to cocaine in Lewis and Fischer rats.

abstract：:The study was designed to determine whether the ability of central oxytocin (OT) to stimulate gonadotropin-releasing hormone (GnRH) on the afternoon of proestrus (PE) in the cycling female rat is mediated at the level of GnRH terminals within the median eminence (ME), or at higher hypothalamic levels where GnRH cell b...
