A potassium channel blocker induces a long-lasting enhancement of corticostriatal responses.

abstract：:Opioids are thought to increase the excitability of hippocampal pyramidal cells by decreasing release of neurotransmitter from inhibitory interneurons. This study compared the actions of the opioid agonist normorphine, and the GABA receptor antagonist bicuculline, on the responses of CA1 pyramidal cells to afferent st...
