Significance of Cerebral blood flow
Cerebral blood flow (CBF) refers to the rate and volume of blood that circulates through the brain, delivering essential oxygen and nutrients to brain tissue. It is crucial for maintaining brain function and can be influenced by various factors including age, anesthesia, and pathological conditions. Changes in CBF can indicate neuronal activity and are measured using advanced imaging techniques. Monitoring CBF is vital during neurosurgical procedures and in assessing conditions like ischemia, stroke, and traumatic brain injury.

Hindu concept of 'Cerebral blood flow'
Cerebral blood flow in Hinduism pertains to the brain's functionality and balance. It can be enhanced through practices like Om chanting and pranayama, which improve cognitive processes and promote tranquility, essential for sleep and overall brain health.
(1) As a result of the decreased cerebral blood flow, the mind becomes quiet, which leads to sleep, as explained within the context of the physiology of sleep and its processes.[1] (2) This is a subject of human whole-brain models, along with oxygen transport, as indicated by research.[2] (3) This is a vital process that can be regulated through acupuncture via angiogenesis and the modulation of vasoactive mediators, which is important in the ischemic area.[3] (4) Pranayama, or regulated breathing, improves cerebral blood flow and oxygenation, improving neuronal activities in the brain centres, including those present in the limbic areas, hypothalamus, and medulla.[4] (5) The enhancement of this is one of the mechanisms through which Om chanting may influence cognitive processes in individuals, as discussed.[5]
The concept of Cerebral blood flow in scientific sources
Cerebral blood flow indicates the blood circulation in the brain linked to neuronal activity, measurable via fMRI, and can be positively affected by meditation, enhancing executive function in specific brain regions.
(1) This refers to the movement of blood within the brain, which was assessed to determine if a particular diagnostic procedure impacted the blood vessels.[6] (2) This is a term that refers to the blood flow in the brain, and a study was performed to study the regional cerebral blood flow in head injury patients with focal contusion and cerebral edema.[7] (3) Cerebral blood flow can be affected by autoregulatory vasodilation of parenchymal vessels, which may be impaired during cerebral vasospasm and lead to cerebral infarction.[8] (4) The imaging of the neck was done to evaluate this parameter and to assess the presence of any abnormalities, such as plaque formation, in the study.[9] (5) This is the blood supply to the brain, and increases in this occur concomitantly with increases in inflammatory response and activation of free radicals in traumatic brain injury.[10]
(1) This is the rate of blood flow to the brain, and an increase can occur during the procedure, potentially leading to complications in certain conditions.[11]
