After a person suffers a stroke, the clock starts ticking for doctors. Every minute that blood flow to the brain remains ...

Engaging core muscles—through movement, exercise or even coughing—may be a key regulator of blood flow in the brain. When the body moves, the contraction of abdominal muscles increases pressure in ...

A new MRI-based index shows that blood flow closely follows cell density across the layered human cortex and captures aspects ...

But this study suggests that circulation is also influenced by mechanical forces originating elsewhere in the body. As ...

Measuring blood flow in the brain is critical for responding to a range of neurological problems, including stroke, traumatic brain injury (TBI) and vascular dementia. But existing techniques, ...

Psychedelics are a class of compounds that alter people's perceptions, mood and mental processes. Recent clinical studies ...

All day long, our brains carry out complicated and energy-intensive tasks such as remembering, solving problems, and making decisions. To supply the energy these tasks require while conserving this ...

A new study in mice describes how the brain rapidly and efficiently increases blood flow to active areas where oxygen and nutrients are needed most. The work shows that the brain relies on a ...

A surprising new study suggests that eating peanuts every day could help support brain health and memory in older adults.

Schematic showing how contraction of abdominal muscles could increase pressure in blood vessels connected to the brain through the spinal column. A new study by researchers at Penn State shows that ...
