Leg exercise is critical to brain and nervous system health

New research shows that using the legs, particularly in weight-bearing exercise, sends signals to the brain that are vital for the production of healthy neural cells. The groundbreaking study fundamentally alters brain and nervous system medicine — gi…

Training compassion ‘muscle’ may boost brain’s resilience to others’ suffering

A new study suggests that as little as two weeks of compassion meditation training — intentionally cultivating positive wishes to understand and relieve the suffering of others — may reduce the distress a person feels when witnessing another’s suffer…

Gauging language proficiency through eye movement

A new study indicates eye movement can reveal the proficiency of people reading English as a second language.

In brain stimulation therapy less might be more

Theoretical and experimental results demonstrate a new insight for optimizing rTMS, one of the common non-invasive magnetic brain stimulation therapies used to treat brain disorders such as depression and neuropathic pain.

Subtle hearing loss while young changes brain function

New research has found that young people with subtle hearing loss — the kind they aren’t even aware of — are putting demands on their brains that typically wouldn’t be seen until later in life.

Mice brain structure linked with sex-based differences in anxiety behavior

Using male individuals has long been a tradition in scientific mice studies. But new research enforces the importance of using a balanced population of male and female mice. Scientists studying the locus coeruleus brain structure in mice unexpectedly f…

Mechanisms of harmful overhydration and brain swelling

We are all familiar with the drawbacks of dehydration, but we rarely hear about the harmful effects of overhydration. Scientists have now uncovered a key piece to the puzzle of how our brains detect hyponatremia and regulate overhydration. The new stud…

Deep space radiation treatment reboots brain’s immune system

NASA and private company SpaceX plan to send humans to Mars within the next 15 years — but need to figure out how to protect astronauts from the dangerous cosmic radiation of deep space. Now neuroscientists have identified a potential treatment for th…

Personalizing therapeutic brain stimulation

A study of epilepsy patients with implanted electrodes provides an unprecedented view of the changes in brain activity created by electrical stimulation. These findings have the potential to improve noninvasive stimulation approaches toward the treatme…

Mice regrow brain tissue after stroke with bioengineered gel

In a first-of-its-kind finding, a new stroke-healing gel helped regrow neurons and blood vessels in mice with stroke-damaged brains, researchers report.
