Cerebral blood flow and metabolism during exercise.
During exercise regional cerebral blood flow (rCBF), as blood velocity in major cerebral arteries and also blood flow in the internal carotid artery increase, suggesting an increase in blood flow to a large part of the brain. Such an increase in CBF is independent of the concomitant increase in blood pressure but is modified by the alteration in arterial carbon dioxide tension (PaCO(2)). Also, ...
متن کاملA lumped parameter model of cerebral blood flow control combining cerebral autoregulation and neurovascular coupling.
Cerebral blood flow regulation is based on a variety of different mechanisms, of which the relative regulatory role remains largely unknown. The cerebral regulatory system expresses two regulatory properties: cerebral autoregulation and neurovascular coupling. Since partly the same mechanisms play a role in cerebral autoregulation and neurovascular coupling, this study aimed to develop a physio...
متن کاملSelective α1-adrenergic blockade disturbs the regional distribution of cerebral blood flow during static handgrip exercise.
Handgrip-induced increases in blood flow through the contralateral artery that supplies the cortical representation of the arm have been hypothesized as a consequence of neurovascular coupling and a resultant metabolic attenuation of sympathetic cerebral vasoconstriction. In contrast, sympathetic restraint, in theory, inhibits changes in perfusion of the cerebral ipsilateral blood vessels. To c...
متن کاملFocussed Research Group Cerebral Blood Flow, Neurovascular Coupling, and Cortical Spreading Depression Organizers:
Due to the complexity of the multiple topics discussed at this workshop, the group of participants possess diverse and complementary expertise. Here is a brief description of the participants. K.C. Brennan (Utah, Neuroscience) Brennan is a neurologist with interests in headache. His research explores the effects of CSD on blood vessels and vice versa. J.C. Chang (Ohio State, Math. Biosciences I...
متن کاملCerebral blood flow and metabolism during exercise: implications for fatigue.
During exercise: the Kety-Schmidt-determined cerebral blood flow (CBF) does not change because the jugular vein is collapsed in the upright position. In contrast, when CBF is evaluated by (133)Xe clearance, by flow in the internal carotid artery, or by flow velocity in basal cerebral arteries, a approximately 25% increase is detected with a parallel increase in metabolism. During activation, an...
