A meta-analysis of 193 brain-imaging studies shows similar gray-matter loss in the brains of people with diagnoses as different as schizophrenia, depression and addiction.

Researchers say that the appearance in the brain of a type of immune cell has been implicated in delayed dementia in mice and humans who have suffered a stroke.

Depressing but true: people are less able to form new brain connections as they grow older. Undergraduate Richie Sapp was part of a team whose research could make it easier for adults to learn, and possibly heal after brain injuries.

A raft of rodent experiments has demonstrated that blood transfusions from a young donor reverse the effects of aging in older recipients over recent years.

A study in mice has found that a commonly used antibiotic can be modified to eliminate the risk that it will cause hearing loss.

Brain cells called microglia chew up toxic substances and cell debris, calm inflammation and make nerve-cell-nurturing substances. New research shows that keeping them on the job may prevent neurodegeneration.

An interdisciplinary team of scientists has convened to map the origins of mental illnesses in the brain and develop noninvasive technologies to treat the conditions. The collaboration could lead to improved treatments for depression, anxiety and post-tra

 

As methods of imaging the brain improve, neuroscientists and educators can now identify changes in children's brains as they learn, and start to develop ways of personalizing instruction for kids who are falling behind.

Results from a brain-imaging study led scientists into a medical mystery going back to 1881, involving a disputed brain pathway discovered by one scientist and ignored by others. The team rediscovered the pathway's original publication in texts in the bas

Radiology researchers have discovered that the brains of patients with chronic fatigue syndrome have diminished white matter and white matter abnormalities in the right hemisphere.

The blocking of endocannabinoids — the brain’s internal versions of marijuana’s psychoactive chemicals — appears to play a role in the early pathology of Alzheimer’s disease.

The New York Stem Cell Foundation awarded pathologist Marius Wernig $200,000 to pursue stem cell research, and neurobiologist Lisa Giocomo $1.5 million to expand her lab and train other scientists.

A team of Stanford Bio-X scientists has restored the ability of adult mice to form new connections in the brain. If the finding works in people, it has the potential to help adults recover from stroke and forms of blindness or to prevent the loss of conne
