New brain chip aids speech and swallowing recovery after injury
US researchers develop a brain implant that sends electrical signals to help restore speech and swallowing in patients with brain injuries.
American researchers have developed a brain implant that can help restore speech and swallowing abilities in patients with brain injuries. The electronic chip works by sending low-frequency electrical signals to the motor thalamus, a deep brain region linked to the motor cortex. According to the University of Pittsburgh, the chip was initially designed to treat uncontrollable tremors, but trials revealed its potential in activating facial and throat muscles.
The researchers noted that deep brain stimulation, which involves electrical signals, is already used to treat certain neurological disorders, including tremors linked to Parkinson's disease.
