Us versus them: Harming the ‘outgroup’ is linked to elevated activity in the brain’s reward circuitry

Humans tend to form groups, which often find themselves in conflict with rival groups. But why do people show such a ready tendency to harm people in opposing groups? A new study led by researchers at Virginia Commonwealth University used functional br…

The lasting symptoms among COVID-19 long haulers

More than two years after the COVID-19 pandemic erupted, scientists have become increasingly aware of a group of patients — so-called ‘long haulers’ — who remain plagued by a combination of symptoms long after the infection passes. In a new study, re…

How the cerebellum modulates our ability to socialize

The cerebellum is essential for sensorimotor control but also contributes to higher cognitive functions including social behaviors. Researchers uncovered how dopamine in the cerebellum modulates social behaviors via its action on D2 receptors (D2R). Th…

Gold ribbon not necessary: Healthy brain and body function are the rewards in this game

Researchers have found that even the oldest adults can benefit from a game-like intervention that targets cognitive and physical function by combining body movement with tasks that stimulate frontal, temporal, and occipital brain activity to prevent ag…

Preadolescents exposed to high levels of air pollution in their first years of life display changes in brain connectivity

Higher exposure to air pollution is associated with higher functional brain connectivity among several brain regions in preadolescents, while exposure to traffic noise was not, according to a study. The findings also identify the first years of life as…

Opioid analgesic fentanyl may cause autism-like behavior in young mice, study finds

A new study reveals that opioid analgesic fentanyl may induce autism-like behaviors in young male and female mice. The findings indicate that reduced expression of the gene Grin2b in the anterior cingulate cortex of the brain following fentanyl treatme…

Brain signal irregularity may provide clues to understanding epileptic process

Researchers propose a new method to differentiate signals from the epileptic focus from those recorded in other parts of the brain without the presence of an epileptic seizure. This technique may help detect epilepsy-induced features from these signals…

Stress accelerates immune aging, study finds

Stress — in the form of traumatic events, job strain, everyday stressors and discrimination — accelerates aging of the immune system, potentially increasing a person’s risk of cancer, cardiovascular disease and illness from infections such as COVID-1…

Staring at yourself during virtual chats may worsen your mood

A new study finds that the more a person stares at themself while talking with a partner in an online chat, the more their mood degrades over the course of the conversation. Alcohol use appears to worsen the problem, the researchers found.

Researchers demonstrate near-non-invasive In-vivo imaging in mouse cortex at an unprecedented depth

A research team has demonstrated in-vivo imaging of fine neuronal structures in mouse cortex through the intact skull at an unprecedented depth of 750 µm below pia, making high-resolution microscopy in cortex near non-invasive and measurably facilitat…
