Mind over matter: Amygdala circuit counteracts pain-driven emotion

Two pathways in the brain converging at the amygdala regulate the anxiety and depression that often accompanies chronic pain, suggests research in male rats. One of these pathways may represent a top-down mechanism that controls negative emotion under …

Brain cells responsible for removing damaged neurons after injury identified

Researchers have discovered that microglia, specialized immune cells in the brain, play a key role in clearing dead material after brain injury. The study reveals that microglia gobble up the remnants of injured neurons, which could prevent the damage …

Brain study reveals why some people fail to stick to their diet

A new study finds that greater gray matter volume in two regions of the brain is linked to greater ability to exercise self-control in food choices.

How does ketamine relieve depression so quickly?

Ketamine has been shown to relieve symptoms of depression quickly. A new study delves into the molecular details and asks how and why.

Brain tingling sensation ‘ASMR’ may benefit health

New research investigates, for the first time, the physiological and psychological benefits of the autonomous sensory meridian response (ASMR) phenomenon.

Highly empathic people have a unique view of music

A study using brain scanning technology concludes that music activates different brain areas for people who demonstrate higher levels of empathy.

How horses perceive and respond to human emotion

A new study shows, for the first time, that horses read and respond to human emotions by integrating the facial expressions with their tone of voice.

What 800 million tweets reveal about our thought patterns

An analysis of 800 million tweets and 7 billion words shows that our thinking throughout the day changes in highly predictable ways.

Scientists discover how brain signals travel to drive language performance

Using transcranial magnetic stimulation and network control theory, researchers have taken a novel approach to understanding how signals travel across the brain’s highways and how stimulation can lead to better cognitive function.

‘Antifreeze’ molecules may stop and reverse damage from brain injuries

The key to better treatments for brain injuries and disease may lie in the molecules charged with preventing the clumping of specific proteins associated with cognitive decline and other neurological problems, researchers report.
