Peter Searson is leading a Johns Hopkins University team that is unravelling how Alzheimer's and other diseases disrupt the blood-brain barrier, the complex interface that allows or blocks the passage ...

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 ...

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, ...

Researchers from Science Tokyo develop a new computational method that combines 4D MRI, CFD, and DA for faster and realistic blood flow analysis in brain aneurysms. To simulate blood flow inside brain ...

A new study suggests that dementia may be driven in part by faulty blood flow in the brain. Researchers found that losing a key lipid causes blood vessels to become overactive, disrupting circulation ...

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, ...

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 ...

Researchers have discovered how newly created neurons depend on blood flow in the adult brain to travel from their site of origin to their final location. The study in mice, published today in eLife, ...
