Not tDCS but fascinating…
Medtronic [a medical device manufacturer] will be developing a 256-channel brain stimulator, not only to stimulate but to record and analyze brain activity and [to] try to modify and synthesize it within the brain.
The ultimate goal is to send patients with memory disorders home with a device implanted into their brain to improve their memory.
How will the study work?
The 256-channel device will be far more than a brain stimulator. It will be an intelligent device that continuously monitors brain function for signals that indicate how well our memory system is operating. As it tracks these signals, in real time, it will use mathematical models of brain function to determine whether and how to stimulate at each of these locations. By cycling very rapidly between recording, analyzing and stimulating, it will try to continuously maintain good memory function in patients with neurological injury or disease.
