Neurovascular coupling
Neurovascular coupling is the process by which the brain's blood flow increases to meet the energy demands of active neurons. When certain brain cells are stimulated, they require more oxygen and nutrients to function effectively. In response, nearby blood vessels dilate, allowing more blood to flow and deliver these essential resources. This coordination ensures that different areas of the brain receive adequate support during various tasks, playing a vital role in overall brain health and function. Essentially, it connects brain activity with blood supply, highlighting the relationship between neural activity and vascular response.

Neurovascular coupling is the process by which blood flow to a specific brain region increases when that area is active or engaged in a task. When neurons in the brain become more active, they require more oxygen and nutrients. In response, blood vessels dilate to supply this increased demand. This connection between brain activity and blood flow is crucial for maintaining healthy brain function and is important for understanding how the brain works in both health and disease. Essentially, it ensures that active brain cells receive the resources they need to function effectively.
