The first step in this process is determining where in the brain the BCI should record from to decode someone’s intended speech.

Currently, BCI devices are only used on individuals with paralysis from ALS or stroke in the brainstem, which leaves them unable to move or communicate. In these patients, BCIs record signals from the frontal lobe. But Broca’s aphasia, which most often affects people after a stroke or brain tumor, results from damage to the frontal lobe of the brain, where speech production and parts of language are processed. So, to help patients with Broca’s aphasia, scientists would likely need to record signals from other areas of the brain.

Researchers at Washington University School of Medicine in St. Louis have enrolled the first participants in an international clinical trial designed to prevent Alzheimer’s.

Alzheimer’s disease is a progressive neurological disorder that primarily affects older adults, leading to memory loss, cognitive decline, and behavioral changes. It is the most common cause of dementia. The disease is characterized by the buildup of amyloid plaques and tau tangles in the brain, which disrupt cell function and communication. There is currently no cure, and treatments focus on managing symptoms and improving quality of life.

A new study suggests that creativity maps onto a common brain circuit and that injury and neurological disease have the potential to unleash creativity. Researchers analyzed 857 participants across 36 fMRI brain imaging studies to identify a common brain circuit for creativity.
