Electrical recordings directly from the human brain show remarkable precision in the coordination of widely distributed regions involved in memory recall, at rest and during sleep.

Assistant professors Amin Arbabian, Michael Lepech, Marco Pavone, Manu Prakash and Sindy Tang awarded grants to help promising junior faculty pursue outstanding research while also improving education.

A computer model of brain function helps explain a 20-year-old finding that the way a single noisy neuron fires in the brain can predict an animal's decisions. It turns out neurons without noise can't learn. The type of learning the group modeled reflects

In addition to being scientifically important, Karl Deisseroth's research makes for some really cool-looking pictures.

Interestingly, and on a cheerier note, one of the biggest themes programmed into the Davos agenda this January was a series of events on the new scientific developments about the brain.

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.

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.

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.

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
