Our brains have a ‘fingerprint’ too

An EPFL scientist has pinpointed the signs of brain activity that make up our brain fingerprint, which — like our regular fingerprint — is unique.

Why do we remember stressful experiences better?

When the brain stores memories of objects, it creates a characteristic pattern of activity for each of them. Stress changes such memory traces.

Discovery of new role for the brain’s immune cells could have Alzheimer’s implications

The immune cells, known as microglia, also help regulate blood flow and maintain the brain’s critical blood vessels, researchers have discovered. The findings may prove important in cognitive decline, dementia and stroke, among other conditions linked …

Study could pave way for creating safer opioids

Researchers may have an uncovered new answers on how to create safer opioids. Design a new opioid to bypass the part of brain that feels pleasure, but retain the analgesic properties, which make opioids one of the most effective pain relievers. Researc…

How the brain ignores distracting information to coordinate movements

Researchers have discovered how neurons in a small area of the mammalian brain help filter distracting or disruptive signals — specifically from the hands — to coordinate dexterous movements. Their results may hold lessons in how the brain filters ot…

Study discovers unique brain signature of intimate partner aggression

A new study used functional magnetic resonance imaging to examine the brain activity of 51 male-female romantic couples as they experienced intimate partner aggression in real time. They found that aggression toward intimate partners was associated wit…

Brain ‘noise’ may hold the keys to psychiatric treatment efficacy

It remains a central challenge in psychiatry to reliably judge whether a patient will respond to treatment. Researchers now show that moment-to-moment fluctuations in brain activity can reliably predict whether patients with social anxiety disorder wil…

Large doses of intensive therapy better for children with cerebral palsy, multi-university study finds

Scientists report that children benefited most from 60 hours of Constraint-Induced Movement Therapy (CIMT) over four weeks. The study also showed that the intensive therapy did not add stress for families.

Brain activity patterns after trauma may predict long-term mental health

The way a person’s brain responds to stress following a traumatic event, such as a car accident, may help to predict their long-term mental health outcomes, according to new research. The study followed more than 3,000 people for up to a year after exp…

Sense of smell is our most rapid warning system

The ability to detect and react to the smell of a potential threat is a precondition of our and other mammals’ survival. Using a novel technique, researchers have been able to study what happens in the brain when the central nervous system judges a sme…
