Pathophysiological significance of T-type Ca2+ channels: expression of T-type Ca2+ channels in fetal and diseased heart.

abstract：:We have demonstrated previously that the ketamine-induced discriminative stimulus effect is likely to reflect the phencyclidine-like psychotomimetic effects. Therefore, the present study was designed to investigate the effects of the antipsychotics and 5-HT2 receptor antagonist on the discriminative stimulus effects o...
