Reader Wave723 writes about an implantable chip that is able to detect and adjust dopamine levels in mice brains. Created by researchers at Case Western Reserve University, the chip, unlike other brain implants, traces the neurotransmitter instead of relying on electrical signals. Wave723 elaborates: This brain implant is a chip that can automatically sense dopamine levels through an electrode that measures the flow of the neurotransmitter through the brain and pH levels. An algorithm within the device calculates whether dopamine levels are within a predetermined range, and if not, the chip sends an electrical impulse to stimulate neurons to produce more. Someday, it might help patients with a variety of disorders including addiction, or Parkinson's disease though a lot more research is needed to be done on neurotransmitter levels in order to reach that point.
