Daily rhythm of cerebral blood flow velocity
Journal of Circadian Rhythms, 2005 Background CBFV (cerebral blood flow velocity) is lower in the morning than in the afternoon and evening. Two hypotheses have been proposed to explain the time of day changes in CBFV: 1) CBFV changes are due to sleep-associated processes or 2) time of ...
