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 Those affected also lead a withdrawn life. Researchers have now found evidence for a gene that is believed to be linked to the illness. It encodes a serotonin …

Neuroscientists pinpoint key gene controlling tumor growth in brain cancers

Investigators have identified a stem cell-regulating gene that affects tumor growth in patients with brain cancer and can strongly influence survival rates of patients. The findings could move physicians closer to their goal of better predicting the pr…

Alcoholism may be caused by dynamical dopamine imbalance

Researchers have identified potential alcoholism mechanisms, associated with altered dopaminergic neuron response to complex dynamics of prefrontal cortex neurones affecting dopamine release.

After heart attack, people with depression twice as likely to die

Studying altruism through virtual reality

A computer-based environment has been developed with the aim to shed light on the origins of altruism. This new study immersed participants in a virtual environment that reproduced a building on fire which they had to evacuate in a hurry, deciding whet…
