Brain implants to map and treat neurological disorders
Our brains are incredible machines capable of extraordinary actions. But sometimes the brain doesn’t work exactly as it should. Nerves that should fire don’t or fire at the wrong time. Deep brain stimulation, which uses electrodes to direct electrical signals to a specific part of the brain in the brain, is used to treat some neurological disorders, including Parkinson’s disease and epilepsy. Newer therapies for depression, anxiety, and addiction would use these electrodes to create a map of electrical activity in the brain that is specific to each patient, allowing researchers to pinpoint what brain activity corresponds with symptoms and target that activity for the treatment.
