Lack of heart rate changes during an attention-demanding task after right hemisphere lesions.
Patients with right hemisphere lesions may be impaired in mobilizing attention and in emotional behavior. If so, autonomic responses to the mobilization of attention should be blunted. This was found when we studied the anticipatory heart rate deceleration that is seen normally in the foreperiod of a warned reaction task.
