抑制不想要的想法,行动和情绪在日常生活中占据中心地位,前额叶皮层被广泛认为是这种抑制控制的来源。我们认为,前额叶皮层的功能最好理解为代表和积极维护抽象信息,如目标,这对其他大脑区域产生两种类型的抑制作用。对某些皮层下区域的抑制采取了定向的、全局的形式,前额叶区域提供了与何时抑制某个区域的所有处理相关的上下文信息。新皮层(和一些皮层下)区域内的抑制采取间接的竞争形式,前额叶区域提供与目标相关的选择的兴奋。这些区别对于理解抑制机制以及如何削弱或改善抑制机制至关重要。
Inhibiting unwanted thoughts, actions and emotions figures centrally in daily life, and the prefrontal cortex is widely viewed as a source of this inhibitory control. We argue that the function of the prefrontal cortex is best understood in terms of representing and actively maintaining abstract information such as goals, which produces two types of inhibitory effects on other brain regions. Inhibition of some subcortical regions takes a directed, global form, with prefrontal regions providing contextual information relevant to when to inhibit all processing in a region. Inhibition within neocortical (and some subcortical) regions takes an indirect, competitive form, with prefrontal regions providing excitation of goal-relevant options. These distinctions are critical for understanding the mechanisms of inhibition and how they can be impaired or improved.
