Central and baroreflex control of heart rate during the wake-sleep cycle in rat
(Sleep, 2001)
Spontaneous fluctuations in Heart Period (HP) and Mean Arterial Pressure (MAP) make it possible to evaluate baroreceptor-heart rate reflex sensitivity (BRS). 30-s sequences of HP and MAP beat-to-beat values were considered ...
Sleep-related brain activation does not increase the permeability of the blood–brain barrier to glucose
(Journal of Cerebral Blood Flow & Metabolism, 2005)
We compared blood-brain barrier (BBB) permeability to glucose between quiet wakefulness and rapid-eye-movement (REM) sleep to assess whether changes in BBB permeability play a role in coupling glucose supply to the physiologic ...
Effects of Acoustic Stimulation on Cardiovascular Regulation During Sleep
(Sleep, 2003)
The interaction of wake-sleep states and acoustic stimulation on cardiovascular regulation was studied on rats implanted with electroencephalogram and electromyogram electrodes and an arterial catheter. Mild acoustic stimuli ...
Brain capillary perfusion in the spontaneously hypertensive rat during the wake-sleep cycle
(Experimental Brain Research, 2004)
Hypertension is accompanied by circulatory changes in the brain and in other vascular districts; at disease onset, these changes may be largely functional and dependent on metabolic and vegetative drives. The wake-sleep ...
Sleep-Related Changes in the Regulation of Cerebral Blood Flow in Newborn Lambs
(Sleep, 2004)
Study Objectives: The interplay between cerebral perfusion pressure (CPP) and vascular resistance leads to fluctuations in cerebral blood flow (CBF). The relationship between fluctuations in CBF and those in CPP provides ...
