Nociceptin Receptor Antagonism Modulates Electrophysiological Markers of Reward Learning.
Using in vivo electrophysiology and a reward-learning task reverse-translated from humans, this study tested the hypothesis that a nociceptin (NOP) receptor antagonist (J-113397) would potentiate behavioral and electrophysiological markers of reward learning in rats. Relative to vehicle, the NOP antagonist modulated electrophysiological markers of reward processing but did not affect response bias toward a more frequently rewarded stimulus. This proof-of-concept study provides initial insights into the effects of NOP receptor antagonism on reward learning, which are consistent with previous findings suggesting that such mechanism is a promising antidepressant target.
期刊介绍:
The central focus of the journal is on research that advances understanding of existing and new neuropsychopharmacological agents including their mode of action and clinical application or provides insights into the biological basis of psychiatric disorders and thereby advances their pharmacological treatment. Such research may derive from the full spectrum of biological and psychological fields of inquiry encompassing classical and novel techniques in neuropsychopharmacology as well as strategies such as neuroimaging, genetics, psychoneuroendocrinology and neuropsychology.
