For neural research, wireless chip shines light on the brain

Researchers have developed a chip that is powered wirelessly and can be surgically implanted to read neural signals and stimulate the brain with both light and electrical current. The technology has been demonstrated successfully in rats and is designe…

Early details of brain damage in COVID-19 patients

Looking at six patients using a specialized magnetic resonance technique, researchers found that COVID-19 patients with neurological symptoms show some of the same metabolic disturbances in the brain as other patients who have suffered oxygen deprivati…

Technology lets clinicians objectively detect tinnitus for first time

A technology called functional near-infrared spectroscopy (fNIRS) can be used to objectively measure tinnitus, or ringing in the ears, according to a new study.

A regular dose of nature may improve mental health during the COVID-19 pandemic

Changes to the brain’s reward system may drive overeating in mice

A combination of innate differences and diet-induced changes to the reward system may predispose some mice to overeat, according to research recently published in JNeurosci.

Chronic alcohol use reshapes the brain’s immune landscape, driving anxiety and addiction

Deep within the brain, a small almond-shaped region called the amygdala plays a vital role in how we exhibit emotion, behavior and motivation; it’s also strongly implicated in alcohol abuse. Now, for the first time, a team has identified important chan…

‘Alarming’ COVID-19 study shows 80 percent of respondents report significant symptoms of depression

A new national survey, looking at how the COVID-19 pandemic has impacted young U.S. adults’ loneliness, reveals ‘significant depressive symptoms’ in 80 percent of participants.

Scientists discover new mechanism controlling brain size

International research has led to the discovery of a new mechanism that controls the size of our brains. The finding, which is based on studies on a rare congenital brain disease, delivers an important piece of data in our knowledge about how the human…

Parasite infection discovery could assist mental health treatments

New research into how a common parasite infection alters human behavior could help development of treatments for schizophrenia and other neurological disorders. T. gondii currently infects 2.5 billion people worldwide and causes the disease Toxoplasmos…
