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.

Brain hardwired to respond to others’ itching

Itching is a highly contagious behavior. When we see someone scratch, we’re likely to feel itchy, too. New research shows contagious itching is hardwired in the brain.

Machine learning writes songs that elicits emotions from its listeners

Music, more than any art, is a beautiful mix of science and emotion. It follows a set of patterns almost mathematically to extract feelings from its audience. Machines that make music focus on these patterns, but give little consideration to the emotio…

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 Those affected also lead a withdrawn life.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.
