This chapter discusses sleep and its relationships to cerebral blood flow. The author has a special interest in changes in blood flow in relation to sleep. The author had shown that in the forearm, going to sleep was associated with widening of the vessels and waking was accompanied by contraction, reflecting, the author hypothesized, displacement of the blood toward the brain. In this chapter the author tests that hypothesis on Catharina X, in whom it is found that waking up is indeed associated with an increase in cerebral volume.
