Implantable neural recording device tracks brain activity over months, enabling long-term study of neural circuits and potential new therapies. The device, developed by researchers at the University of California, Berkeley, can record the activity of up to 1,024 neurons simultaneously for up to six months. This is a significant improvement over existing devices, which can only record from a few neurons at a time and for a few hours or days. The new device could be used to study a wide range of brain disorders, including epilepsy, Parkinson’s disease, and Alzheimer’s disease. It could also be used to develop new therapies for these disorders, such as deep brain stimulation and optogenetics.
