The consequences of brain trauma on local cerebral blood flow (ICBF) have been documented clinically and in several experimental models [1, 2, 3, 4,7]. Perfusion deficits and cerebral ischemia are believed to represent import ant secondary injury mechanisms after traumatic brain injury (TEl) [5,8].

Vestibular effects on cerebral blood flow [PDF]
AbstractHumans demonstrate a number of unique adaptations that allow the maintenance of blood pressure and brain blood flow after transition to the upright position. While these adaptations maintain heart-level mean arterial pressure similar to supine values, the brain remains ~30 cm above the heart, resulting in a ~25% decrease in perfusion pressure ...

Cerebral blood flow decrease as an early pathological mechanism in Alzheimer's disease
Therapies targeting late events in Alzheimer’s disease (AD), including aggregation of amyloid beta (Aβ) and hyperphosphorylated tau, have largely failed, probably because they are given after significant neuronal damage has occurred.

On the Normalization of Cerebral Blood Flow [PDF]
Cerebral blood flow (CBF) is the most common parameter for the quantification of brain's function. Literature data indicate a widespread dispersion of values that might be related to some differences in the measurement conditions that are not properly taken into account in CBF evaluation.

Regulation of Cerebral Blood Flow [PDF]
The control of cerebral blood flow is complex, and only beginning to be elucidated. Studies have identified three key regulatory paradigms. The first is cerebral pressure autoregulation, which maintains a constant flow in the face of changing cerebral perfusion pressure.

An Analysis of Resting-State Functional Transcranial Doppler Recordings from Middle Cerebral Arteries [PDF]
Functional transcrannial Doppler (fTCD) is used for monitoring the hemodynamics characteristics of major cerebral arteries. Its resting-state characteristics are known only when considering the maximal velocity corresponding to the highest Doppler shift (

Fractal Rigidity in Migraine [PDF]
We study the middle cerebral artery blood flow velocity (MCAfv) in humans using transcranial Doppler ultrasonography (TCD). Scaling properties of time series of the axial flow velocity averaged over a cardiac beat interval may be characterized by two ...
