Researchers at UC San Francisco and UC Berkeley have developed a brain-computer interface (BCI) that has enabled a woman with severe paralysis from a brainstem stroke to speak through a digital avatar.

It is the first time that either speech or facial expressions have been synthesized from brain signals. The system can also decode these signals into text at nearly 80 words per minute, a vast improvement over commercially available technology.

Edward Chang, MD, chair of neurological surgery at UCSF, who has worked on the technology, known as a brain computer interface, or BCI, for more than a decade, hopes this latest research breakthrough, appearing Aug...

Our behavior is controlled through neural circuits in the brain. Molecular disturbances can lead to stereotypical behavior, as seen in neuropsychiatric disorders such as obsessive-compulsive and autism spectrum disorders.

A research team has now demonstrated that the absence of two proteins, Intersectin1 and Intersectin2, in mice leads to disrupted neural signaling and compulsive repetitive behavior, which is also observed in patients with Intersectin 1 mutations. This supports the idea that such defects can cause neuropsychiatric diseases. The study is published in Proceedings of the National Academy of Sciences.

Our brain is essentially our body’s computer...

An analysis of a clinical trial of more than 2,500 people with Type 2 diabetes and kidney disease found that high levels of four biomarkers are strongly predictive for the development of heart and kidney issues.

A simple blood test may predict the risk of progressive heart and kidney disease in people with Type 2 diabetes and kidney disease, according to new research published today in the American Heart Association’s flagship journal Circulation.

“High levels of certain biomarkers are indicators of heart and kidney complications and may help predict future risk of disease progression,” said lead author James Januzzi, M.D...

AI-powered model using chest Xrays helps develop biomarkers for aging. Osaka Metropolitan University scientists have developed an AI model that accurately estimates a patient’s age, using chest radiographs of healthy individuals collected from multiple facilities...
