Exercise challenges cerebral autoregulation (CA) by a large increase in pulse pressure (PP)
that may make systolic pressure exceed what is normally considered the upper range of CA …

Background and Purpose—Animal studies provide strong evidence that aerobic exercise
training positively influences cerebral blood flow, but no human studies support the use of …

Transcranial Doppler ultrasound-determined middle (MCA) and anterior (ACA) cerebral
artery mean flow velocities (Vmean) and pulsatility indexes (PI) were measured during “no …

The coupling of cerebral blood flow (CBF) to neuronal activity is well preserved during
evolution. Upon changes in the neuronal activity, an incompletely understood coupling …

Conflicting data exist on the role of nitric oxide (NO) in cerebral blood flow (CBF)
autoregulation. Previous studies involving human and animal subjects seem to indicate that …

Blood flow (BF) increases with increasing exercise intensity in skeletal, respiratory, and
cardiac muscle. In humans during maximal exercise intensities, 85% to 90% of total cardiac …

Cerebral blood flow (CBF) regulation can be impaired in acute ischemic stroke but the
combined effects of dynamic cerebral autoregulation (CA), CO2 cerebrovascular reactivity …

The brain uses~ 20% of available oxygen for normal function, making tight regulation of
blood flow and oxygen delivery critical for survival [133]. In a normal physiological state, total …

Recent studies from our group and others using quantitative fMRI methods have found that
variations of the coupling ratio of blood flow (CBF) and oxygen metabolism (CMRO2) …

Long-term exercise interventions have been shown to be a potent trigger for both
neurogenesis and vascular plasticity. However, little is known about the underlying temporal …
