The selective effects of somatostatin- and GABA-mediated transmissions on voltage gated Ca2+ channel immunoreactivity in the gerbil hippocampus.

abstract：:Previous research has suggested the potential involvement of the hypothalamic-pituitary-adrenal (HPA) axis in psychostimulant reinforcement. In particular, we have found significant correlations between electric footshock-induced increases in plasma corticosterone and the acquisition, or lack thereof, of intravenous c...
