A new study has found that light therapy applied to mice during deep sleep increased the brain’s ability to clear away beta-amyloid protein, which may lead to a drug-free, non-invasive treatment for Alzheimer's disease.

When you take 800,000 human brain cells, wire them into a biological hybrid computer chip, and demonstrate that it can learn faster than neural networks, people have questions. We speak to Dr. Brett Kagan, Chief Scientific Officer at Cortical Labs.

Researchers have gained new insights into largely overlooked circular RNAs in brain cells and the crucial role they play in diseases like Alzheimer’s and Parkinson’s, opening the door to developing diagnostic tests and treatments for them.

Following years of controversy, including whistleblowers reporting of rushed experimental “hack jobs” that resulted in as many as 1,500 animal fatalities, Elon Musk's brain-chip implant company has begun recruiting for its landmark first human trial.

Two months on from it being declared safe by the FDA, aspartame is again making headlines for the wrong reasons, this time for its potential negative impact on learning and memory. In a mice study, these cognitive impairments were passed on to young.

Researchers have found that an intranasal drug, currently being tested as an MS treatment, reduced brain inflammation and improved cognition in mice with Alzheimer’s disease, independent of the amount of beta-amyloid plaques present.

Using brain imaging, researchers have found that obsessive-compulsive disorder affects particular areas of the brain involved in processing certainty during the decision-making process, providing greater insight into this enigmatic condition.

A study has found that targeting specific brain areas with ultrasound causes functional changes that last up to an hour. It paves the way for developing non-invasive methods of treating mental health conditions such as depression and anxiety.

Researchers have discovered the mechanism by which a cluster of astrocytes, specialized brain cells, in the hypothalamus cause obesity in mice. Their findings could lead to a new obesity treatment that doesn't require a reduction in food intake.

Scientists have discovered how a unique kind of cell death, due to iron toxicity, creates a snowball effect that advances cognitive decline. With this finding, a whole new approach to treatment could be developed.

In an effort to find new treatments to halt the progression of Alzheimer's disease, scientists have landed on a molecule that can dial down the process that produces brain inflammation – something believed to be inextricably linked to cognitive decline.

Researchers discovered the world’s first case of a new human parasitic infection, pulling a live roundworm from a woman's brain. They say the case highlights the risks posed by zoonotic diseases caused by pathogens that jump from animals to humans.
