Effects of pentobarbital and progesterone on random ratio responding in male and female rats.

abstract：RATIONALE:The cerebral microdialysis technique has been widely used to monitor the release of 5-hydroxytryptamine (5-HT). The extracellular concentration of 5-HT has generally been shown to change after pharmacological manipulation as expected.
