许多认知任务都会激活扣带皮层。这些任务包括错误检测、分散注意力、冲突和单词生成任务。然而，扣带回的确切区域被发现是活跃的有所不同。这可能是由于受试者、实验室、数据分析或任务条件的差异造成的。目前的研究使用了两种非常不同的任务来激活扣带回，并比较了来自相同受试者和相同试验的数据，以确定扣带回激活是否存在时间和空间差异。选择的任务是生成一个名词的使用和反馈，错误是在生成所需的时间窗口。采用高密度脑电记录技术，在正确反馈与错误反馈、产生反馈与重复反馈的差异波中记录扣带回激活的时程。这两项任务都产生了与扣带回激活一致的活动。然而，这两项任务在不同领域产生了活动。这些数据是一致的想法，即扣带回激活区域的差异在认知任务之间的不同，而不仅仅是由于受试者和实验室的差异。(C)北京：科学出版社.
Many cognitive tasks have activated areas of the cingulate cortex. These include error detection, divided attention, conflict, and word generation tasks. However the exact area of the cingulate found to be active has differed. This could be due to difference in subjects, laboratories, data analysis, or task conditions. The current study uses two very different tasks known to activate the cingulate and compares data from the same subjects and same trials to see whether there are temporal and spatial distinctions in cingulate activations. The tasks chosen were generation of the use of a noun and feedback that an error was made in the time window required for generation. High-density electrical recording was used to trace the time course of cingulate activation in the difference waves between correct and error feedback and between generate and repeat. Both tasks produced activity that is consistent with cingulate activation. However, the two tasks produced activity in different areas. These data are consistent with the idea that differences in areas of the cingulate activated differ between cognitive tasks and are not merely due to subject and laboratory differences.
