Exercise spurs neuron growth and rewires the brain, helping mice forget traumatic and addictive memories

Researchers have found that increased neuron formation and the subsequent rewiring of neural circuits in the hippocampus through exercise or genetic manipulation helps mice forget traumatic or drug-associated memories. The findings could offer a new ap…

Brain ‘assembloids’ mimic human blood-brain barrier

Major advance promises to accelerate the understanding and improved treatment of a wide range of brain disorders, including stroke, cerebral vascular disorders, brain cancer, Alzheimer’s disease, Huntington disease, Parkinson’s disease, and other neuro…

New AI tool to help beat brain tumors

A new AI tool to more quickly and accurately classify brain tumors has been developed.

Seeing not just with the eyes: Degree of arousal affects perception

The brain modulates visual signals according to internal states, as a new study by neuroscientists reveals.

Researchers develop ‘game-changing’ blood test for stroke detection

Stroke is the leading cause of disability worldwide and the second leading cause of death, but the right early intervention can prevent severe consequences. Scientists developed a new test by combining blood-based biomarkers with a clinical score to id…

Different brain structures in females lead to more severe cognitive deficits after concussion than males

Important brain structures that are key for signaling in the brain are narrower and less dense in females, and more likely to be damaged by brain injuries, such as concussion. Long-term cognitive deficits occur when the signals between brain structures…

Unique brain circuit is linked to Body Mass Index

Why can some people easily stop eating when they are full and others can’t, which can lead to obesity? A new study has found one reason may be a newly discovered structural connection between two regions in the brain that appears to be involved in regu…

Under stress, an observer is more likely to help the victim than to punish the perpetrator

Being stressed while witnessing injustice may push your brain towards altruism, according to a new study.

Singing repairs the language network of the brain after a cerebrovascular accident

Singing rehabilitates speech production in post-stroke aphasia. Researchers investigated the rehabilitative effect of singing on the brain.

How does the brain turn waves of light into experiences of color?

Perceiving something — anything — in your surroundings is to become aware of what your senses are detecting. Today, neuroscientists identify, for the first time, brain-cell circuitry in fruit flies that converts raw sensory signals into color percept…
