在目标定向行为中,前额叶皮质(PFC)对许多皮质和皮质下区域进行自上而下的控制。PFC功能障碍与许多障碍有关,这些障碍涉及认知表现、注意力、动机和/或冲动控制方面的缺陷。在这些障碍中,一个共同的主题是PFC的神经调节被扰乱。从解剖学上讲,PFC与几乎所有的神经调节中心都是相互联系的。最近对PFC神经元的体内和体外研究发现,前额叶投射神经元的亚群可以根据它们的远程投射靶点分为不同的亚群。这些亚群在连接性、内在特性和对神经调节剂的反应方面有所不同。在这篇综述中,我们概述了PFC中亚回路特异性神经调节的证据,并描述了在目标定向行为中选择性神经调节对行为状态的一些功能后果。
During goal-directed behavior, the prefrontal cortex (PFC) exerts top-down control over numerous cortical and subcortical regions. PFC dysfunction has been linked to many disorders that involve deficits in cognitive performance, attention, motivation, and/or impulse control. A common theme among these disorders is that neuromodulation of the PFC is disrupted. Anatomically, the PFC is reciprocally connected with virtually all neuromodulatory centers. Recent studies of PFC neurons, both in vivo and ex vivo, have found that subpopulations of prefrontal projection neurons can be segregated into distinct subcircuits based on their long-range projection targets. These subpopulations differ in their connectivity, intrinsic properties, and responses to neuromodulators. In this review we outline the evidence for subcircuit-specific neuromodulation in the PFC, and describe some of the functional consequences of selective neuromodulation on behavioral states during goal-directed behavior.
