With microplastics now permeating our food and our bodies, researchers are keen to assess the potential damage these tiny fragments could be doing. A new study shows how plastics may lead to dangerous ...

Microplastics in the bloodstream may cause blockages the brain and affect our brain functioning and behavior, according to recent research. Environmental biologists tested the effects of microplastics ...

Psilocybin is a psychedelic drug with promising clinical applications for treating mood disorders and substance abuse ...

Researchers have discovered that increased blood flow leads to stiffness in the hippocampus, a region of the brain that plays important roles in learning and memory. The hippocampus is one of the ...

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 ...

Researchers have, for the first time, visualized the full network of blood vessels across the cortex of awake mice, finding that blood vessels rhythmically expand and contract leading to 'waves' ...

Though it accounts for just two percent of the body’s weight, the brain consumes a whopping 20% of its total energy. To get the energy it needs for more complicated tasks, the brain has evolved a ...

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 ...

While the exact causes of neurodegenerative brain diseases like Alzheimer's and dementia are still largely unknown, researchers have been able to identify a key characteristic in affected brains: ...

A team of UVM scientists led by Mark Nelson, Ph.D., from the Larner College of Medicine at the University of Vermont, has uncovered a novel mechanism that reshapes our understanding of how blood flow ...

A wearable ultrasound patch could soon be saving lives, by monitoring the blood flow in hospital patients' brains. The device is only about the size of a postage stamp plus it works continuously, ...

Sildenafil- known most commonly as ‘viagra’- improves brain blood flow and blood vessel function in patients at risk of vascular dementia. The findings may pave the way for treatment and prevention ...
