Pulsatile microvascular blood flow imaging by short-time Fourier transform analysis of ultrafast laser holographic interferometry [PDF]

, 2015
We report on wide-field imaging of pulsatile microvascular blood flow in the exposed cerebral cortex of a mouse by holographic interferometry. We recorded interferograms of laser light backscattered by the tissue, beating against an off-axis reference ...

Cerebral blood flow predicts differential neurotransmitter activity

bioRxiv, 2017
Application of metabolic magnetic resonance imaging measures such as cerebral blood flow in translational medicine is limited by the unknown link of observed alterations to specific neurophysiological processes. In particular, the sensitivity of cerebral

Relationship between cognitive function and regulation of cerebral blood flow

Journal of Physiological Sciences, 2017
Ageing is the primary risk factor for cognitive deterioration. Given that the cerebral blood flow (CBF) or regulation of cerebral circulation is attenuated in the elderly, it could be expected that ageing-induced cognitive deterioration may be affected ...

Vestibular Effects on Cerebral Blood Flow [PDF]

, 2011
Background: Humans demonstrate a number of unique adaptations that allow for the maintenance of blood pressure and brain blood flow when upright. While several physiological systems, including cerebral autoregulation, are involved in this adaptation the ...

Investigating the Relationship between Cerebral Blood Flow and Cognitive Function in Hemodialysis Patients.

Journal of the American Society of Nephrology, 2018
BACKGROUND The immediate and longer-term effects of hemodialysis on cerebral circulation, cerebral structure, and cognitive function are poorly understood. METHODS In a prospective observational cohort study of 97 adults (median age 59 years) receiving

Aerobic exercise training increases cerebral blood flow in postmenopausal women

Artery Research, 2012
Background: Age-related decrease in cerebral blood flow is a risk factor for cognitive decline. Aerobic exercise training improves vascular and cognitive functions.

Is High Blood Pressure Self-Protection for the Brain? [PDF]

, 2016
Rationale: Data from animal models of hypertension indicate that high blood pressure may develop as a vital mechanism to maintain adequate blood flow to the brain.

Hypothalamic-pituitary dysfunction in severe traumatic brain injury long-term outcomes

Chinese Journal of Contemporary Neurology and Neurosurgery
The incidence of hypothalamic-pituitary dysfunction in patients with severe traumatic brain injury (sTBI) reaches up to 40%. However, it is often masked by clinical manifestations similar to those of sTBI, leading to underdiagnosis and misdiagnosis ...
