有证据表明,右下额叶皮层(IFC)在反应抑制中起着专门的作用。然而,最近的研究结果表明,该区域在注意力控制中发挥着更广泛的作用。在这里,我们使用功能性磁共振成像检查的功能性作用的注意,抑制,并在2个实验中,采用新的变化的去/不去任务的反应控制的权利IFC。在这两个实验中,我们观察到右丘脑/IFC的分级反应,从而增加反应控制需求导致激活增加。结果是一致的假设,这一地区发挥了关键作用,自下而上的,自上而下的,响应相关的信息,以促进灵活的,目标导向的行为的整合。
Evidence suggests that the right inferior frontal cortex (IFC) plays a specialized role in response inhibition. However, more recent findings indicate a broader role for this region in attentional control. Here, we used functional magnetic resonance imaging to examine the functional role of the right IFC in attention, inhibition, and response control in 2 experiments that employed novel variations of the go/no-go task. Across the 2 experiments, we observed a graded response in the right insula/IFC, whereby increasing response control demands led to an increase in activation. The results are consistent with the hypothesis that this region plays a key role in the integration of bottom-up, sensory information with top-down, response-related information to facilitate flexible, goal-directed behavior.
