Algorithm for large-scale brain simulations

Researchers have made a decisive step towards being able to simulate brain-scale networks on future supercomputers of the exascale class. The breakthrough algorithm allows larger parts of the human brain to be represented, using the same amount of comp…

Hold my hand: Touching may ease pain by syncing brainwaves

A new study examines what happens in the brains of romantic partners as one of them is going through physical pain and the other is trying to comfort them.

Genes for age-linked brain deterioration identified

A group of genes and genetic switches involved in age-related brain deterioration have been identified. The research found that changes to one of these genes, called Dbx2, could prematurely age brain stem cells, causing them to grow more slowly.

Depression: ‘Orphan’ brain receptor may be to blame

New research furthers our understanding of the neurological causes of depression and brings us closer to developing new treatments for the condition.

How long-term depression alters the brain

Research has shown that depression is tied to biological changes in the brain. But do such changes worsen over time, and are current treatments adequate?

Anxiety may help you to survive a heart attack

Research suggests that generalized anxiety disorder might protect some people after a heart attack, as the psychiatric condition may improve survival.

Can déjà vu tell us what’s coming next?

Déjà vu — that uncanny ‘I’ve seen this before’ experience — is sometimes accompanied by a feeling that you can tell what’s coming next. But can you?

How do our brains tell us we are thirsty?

Feeling thirsty is a primal and unmistakable urge. A new study unpicks the neural mechanisms that make up this feeling, and the story is a complex one.

In pursuit of pleasure, brain learns to hit the repeat button

In a scientific first, researchers have observed in mice how the brain learns to repeat patterns of neural activity that elicit the all-important feel-good sensation. This research offers key insights into how brain activity is shaped and refined as an…

Networks of brain activity predict vulnerability to depression

Tapping into the electrical chatter between different regions of the brain may provide a new way to prevent and treat depression. Scientists showed that mice that were more susceptible to developing depression-like symptoms displayed different networks…
