Abstract In 1959, Niels Lassen illustrated the cerebral autoregulation curve in the classic
review article entitled Cerebral Blood Flow and Oxygen Consumption in Man. This concept …

Understanding the contribution of the autonomic nervous system to cerebral blood flow
(CBF) control is challenging, and interpretations are unclear. The identification of calcium …

Purpose Patients with dysautonomia often experience symptoms such as dizziness,
syncope, blurred vision and brain fog. Dynamic cerebral autoregulation, or the ability of the …

Cerebral hemodynamics, eg, cerebral blood flow, can be measured and quantified using
many different methods, with transcranial Doppler ultrasound (TCD) being one of the most …

The cerebral circulation responds differently to increases in mean arterial pressure (MAP),
compared to reductions in MAP. We tested the hypothesis that this directional sensitivity is …

High-intensity interval training (HIIE) may present unique challenges to the cerebrovascular
system in individuals post-stroke. We hypothesized lower middle cerebral artery blood …

The blood-brain barrier (BBB) is located at the interface between the vascular system and
the brain parenchyma, and is responsible for communication with systemic circulation and …

The cerebral pressure-flow relationship has directional sensitivity, meaning the
augmentation in cerebral blood flow is attenuated when mean arterial pressure (MAP) …

Directional sensitivity, the more efficient response of cerebral autoregulation to increases,
compared to decreases, in mean arterial pressure (MAP), has been demonstrated with …

New Findings What is the central question of this study? Does habitual exercise modality
affect the directionality of the cerebral pressure–flow relationship? What is the main finding …
