Reversal of triazolam- and zolpidem-induced memory impairment by flumazenil.

abstract：BACKGROUND AND RATIONALE:More than two decades ago, Wise proposed his "anhedonia hypothesis" to explain the role of dopamine in motivated behaviors. The hypothesis posits that dopamine mediates the pleasure experienced by reward obtainment. However, some experimental findings have contested this hypothesis and several ...
