虽然许多研究表明前扣带皮层和前额叶皮层都参与了注意力控制，但它们参与的性质仍然存在争议。在这里，我们确定他们在注意力控制中的相对参与程度取决于冲突发生时的处理水平（例如，无反应）。结合使用的封锁和快速演示事件相关的功能磁共振成像技术，我们比较了神经活动在不一致的Stroop试验类型，产生冲突，在不同的处理水平。我们的数据表明，前扣带回和右前额叶皮层参与注意控制主要限于反应冲突的情况下，而左前额叶皮层的参与扩展到非反应水平的冲突的发生。(C)2001年，爱思唯尔科学。All rights reserved.
While numerous studies have implicated both anterior cingulate and prefrontal cortex in attentional control, the nature of their involvement remains a source of debate. Here we determine the extent to which their relative involvement in attentional control depends upon the levels of processing at which the conflict occurs (e.g., response, non-response). Using a combination of blocked and rapid presentation event-related functional magnetic resonance imaging techniques, we compared neural activity during incongruent Stroop trial types that produce conflict at different levels of processing. Our data suggest that the involvement of anterior cingulate and right prefrontal cortex in attentional control is primarily limited to situations of response conflict, while the involvement of left prefrontal cortex extends to the occurrence of conflict at non-response levels.
