There is considerable utility in the use of transcranial Doppler ultrasound (TCD) to assess
cerebrovascular function. The brain is unique in its high energy and oxygen demand but …

The examination of blood flow velocity (BFV) changes during the performance of mental
tasks is one of the applications of transcranial Doppler (TCD) ultrasonography. The purpose …

Changes in cerebral blood oxygenation due to functional activation of the primary
sensorimotor cortex during a unilateral finger opposition task were simultaneously mapped …

Objective To study the mechanisms underlying recovery from middle cerebral artery
infarction in 7 patients with an average age of 53 years who showed marked recovery of …

We studied cerebral hemodynamic response to a sequential motor task in 56 subjects to
investigate the time course and distribution of blood oxygenation changes as monitored by …

Background and Purpose—Functional transcranial Doppler ultrasonography (fTCD) can
assess event-related changes in cerebral blood flow velocities and, by comparison between …

Functional transcranial Doppler sonography (fTCD) adds to the techniques of functional
imaging. fTCD measures cerebral perfusion changes related to neural activation in a way …

Functional transcranial Doppler sonography (fTCD) is used to measure changes in brain
perfusion during different states of brain activity by evaluating flow velocities within the major …

In the brain, increased neural activity is correlated with increases of cerebral blood flow and
tissue oxygenation. However, how cerebral oxygen dynamics are controlled in the behaving …

The dynamic relationship between spontaneous fluctuations of arterial blood pressure (ABP)
and corresponding changes in crebral blood flow velocity (CBFV) is studied in a population …
