Youth-associated protein helps restore healthy function in immune cells in the aging brain

Researchers at the Icahn School of Medicine at Mount Sinai have identified a role for the youth-associated protein TIMP2 in supporting the healthy function of microglia, the brain's resident immune cells.

Curiosity has its own neural signal: Brain separates valuable information from water rewards in mice

Often, humans and other animals seek information that can help them complete tasks and attain desired rewards. In some cases, however, they seek information driven simply by curiosity and a desire to obtain knowledge for ...

Researchers identify possible marker of suicidal thoughts

Researchers at the Netherlands Institute for Neuroscience have identified a possible biological marker linked to severe suicidal thoughts. The finding, published in The British Journal of Psychiatry, may also help explain ...

Electric fields offer new hope against aggressive brain cancer

More than a decade ago, Dr. Matthew Hebb was treating patients with Parkinson's disease using deep brain stimulation by implanting tiny electrodes into the brain and delivering electrical signals to control tremors. He wondered ...

Got ice‑cream brain freeze? Here's what is happening

With temperatures forecast to reach around 37°C (99°F) in places, reaching for an ice cream or an icy drink might seem like an excellent idea. There is, however, one small hazard to eating your frozen treat with too much ...

A new target in the gut for reducing Alzheimer's risk

A compound produced by bacteria in many people's digestive tracts increases the risk of developing Alzheimer's disease and speeds cognitive decline in dementia patients, making it a potential target for a treatment that could ...

Potential language-specific brain network identified

The language network in your brain can be seen, even if you aren't saying a word. For a study published in Nature Communications, researchers used data from more than 1,900 functional magnetic resonance imaging (fMRI) scans ...

Sensory overload in kids has distinct neurobiological roots

Overreactions to ordinary sensory stimuli—a scratchy shirt tag, a roaring vacuum cleaner, an unfamiliar smell—are commonly associated with autism. But in fact, an estimated 15% to 20% of children experience such reactions, ...

How brain ripples help support working memory

Research from scientists at the University of California San Diego School of Medicine and collaborators has shed new light on how the human brain coordinates working memory, the process in which the brain encodes information ...

One of the oldest psychedelics meets modern brain imaging

For millennia, people have used the psychedelic mescaline as a spiritual and religious tool. Mescaline is a naturally occurring chemical found in cacti, mainly peyote cacti, that are located in the Southwest United States ...

Why brains lose their flexibility in psychiatric conditions

Individuals with psychiatric conditions show reduced flexibility in their brain network dynamics, according to a new Rutgers study. The human brain is organized into networks that can adaptively shift and reorganize to meet ...

New brain model links blood flow to Alzheimer's protein spread

Alzheimer's disease is not only about the accumulation of toxic proteins in the brain. A growing number of studies indicate that the health of cerebral blood vessels may also play a decisive role in the onset and progression ...

How autistic brains process faces differently

Researchers have conducted one of the most comprehensive studies on how the autistic brain processes faces. Some hallmark characteristics of autism include tendencies to avoid looking at others' faces and to make less eye ...

What the brain is doing when we're unaware of our actions

Hal Blumenfeld, MD, Ph.D., the Mark Loughridge and Michele Williams Professor of Neurology at Yale School of Medicine (YSM), got out of the pool one afternoon and couldn't find his watch. He was certain he'd left it at the ...
