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

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.

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 ...

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 ...

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 ...

The effect of end-range cervical rotation on vertebral and internal carotid arterial blood flow and cerebral inflow: a sub analysis of an MRI study [PDF]

, 2015
Introduction: Cervical spine manual therapy has been associated with a small risk of serious adverse neurovascular events, particularly to the vertebral arteries. Sustained end-range rotation is recommended clinically as a pre-manipulative screening tool;

Laser speckle contrast imaging for blood flow monitoring in predicting outcomes after cerebral ischemia-reperfusion injury in mice

BMC Neuroscience, 2022
Background In the treatment of ischemic cerebral stroke (ICS), most conventional treatments, including carotid endarterectomy and carotid artery stenting, may cause cerebral ischemia-reperfusion injury (CIRI).
