Quizplus · Accepted Answer

In order to draw conclusions about the activity of specific brain areas during a task, it is important to have recordings from the same areas during a comparison task. This allows researchers to differentiate between activity that is specific to the task and activity that may be related to general cognitive or sensory processes. Recordings from other parts of the body or comments from the experimenter or participant are unlikely to provide relevant information about brain activity in this context.
