This chapter concerns the response of the cerebral circulation during increased mental activity and with emotional and sensory perceptions. It is a great challenge to separate the variations of blood flow limited to the brain from those that involve the entire vascular system. It is noted that changes during the waking state depend very much on the vigorousness of the mental activity more than on going from rest to full activity. A study is carried out on Bertino, comparing the hydrosphygmograph of the forearm with the pulsing of the brain. A variation is noted with a change in emotion.
