The paired-image subtraction technique is used by cognitive neuroscientists to isolate the brain activity specifically associated with a cognitive task, such as reading, by subtracting the brain activity recorded during a control task from the activity recorded during the task of interest. This helps in identifying the areas of the brain that are specifically involved in the cognitive process being studied, filtering out unrelated activity.
