Social phobia: Indication of a genetic cause

People with social anxiety avoid situations in which they are exposed to judgment by others. Those affected also lead a withdrawn life and maintain contact above all on the Internet.

Why do we feel itchy when seeing others scratch?

It can be hard to resist scratching when seeing another person do it. New research finds that this is because our brain is hardwired to do so.

Brain networks at rest are ready for action, researchers suggest

Brain networks at rest appear to be waiting in a state of potentiation to execute even the simplest of behaviors, report researchers.

A closer look at brain organoid development

Researchers already have succeeded in growing so-called ‘cerebral organoids’ in a dish — clusters of cells that self-organize into small brain-like structures. Scientists have now further characterized these organoids. They demonstrate that, like in t…

Anxiety is a stronger harbinger of alcohol problems than stress

Stress and anxiety are widely believed to contribute to drinking. Alcohol is thought to reduce tension caused by stress (the “flight or fight” response) as well as alleviate the unpleasant symptoms of anxiety (anticipation of the unpredictable, impendi…

Brain is 10 times more active than previously measured

A new study could change scientists’ understanding of how the brain works — and could lead to new approaches for treating neurological disorders and for developing computers that ‘think’ more like humans.

How big brains evolved could be revealed by new mathematical model

A new mathematical model could help clarify what drove the evolution of large brains in humans and other animals, according to a study.

Dopamine neurons factor ambiguity into predictions enabling us to ‘win big and win often’

In the struggle of life, evolution rewards animals that master their circumstances, especially when the environment changes. The recipe for success is: win big, and win often. Success depends on the ability to learn. Researchers describe how dopamine-r…

Hard choices? Ask your brain’s dopamine

Researchers have learned how dopamine governs ongoing decisions, yielding insights into Parkinson’s, drug addiction.

Researchers discover how neurons tell each other to die under trauma, disease

Neuroscientists have found that healthy neurons receive messages from injured neighbors that can lead to death. If they can block these messages from getting through, they may be able to slow the progress of neurodegenerative diseases.
