Dec 19th 2024, 15:30

Inflammation in the hippocampus -- the brain's memory center -- significantly alters motivation and behavior in mice, according to new research.

Dec 19th 2024, 15:22

New discoveries about the severe developmental disorder known as Rett syndrome could open the door to better treatments for the devastating, life-shortening condition.

Dec 18th 2024, 17:48

Dyslexia is a common learning difficulty in which genes often play a role. How do genes associated with dyslexia relate to brain structure in the general population? In a large-scale study, a team of scientists found that genetic variants that increase the chance of dyslexia were associated with differences in brain areas involved in motor coordination, vision, and language.

Dec 18th 2024, 17:47

People with breathing problems during sleep may have a larger hippocampus, the area of the brain responsible for memory and thinking, according to a new study. The study, which included mostly Latino people, also found that those with lower oxygen levels during sleep had changes in the deep parts of the brain, the white matter, a common finding of decreased brain health that develops with age.

Dec 18th 2024, 13:21

Artificial intelligence (AI) systems tend to take on human biases and amplify them, causing people who use that AI to become more biased themselves, a new study finds.

Dec 18th 2024, 13:17

To identify and follow blood vessel-related changes in the brain that contribute to cognitive impairment and dementia, researchers and clinicians typically rely on MRI to evaluate 'downstream' biological markers -- those at the end of a cascade of events. But a new multicenter study could lead to a cost-effective blood test to identify changes occurring near the top of the chain, potentially identifying at-risk patients at an earlier stage.

Dec 17th 2024, 14:09

Researchers have revealed how an overlooked type of indirect brain damage contributes to ongoing disability after a stroke. The paper shows how the thalamus -- a sort of central networking hub that regulates functions such as language, memory, attention and movement -- is affected months or years after a person has experienced a stroke, even though it was not directly damaged itself. The findings may lead to new therapies that could reduce the burden of chronic stroke, which remains one of the leading causes of disability in the world.
