Researchers in the electrical engineering at the University of Arkansas have developed a wireless, implantable biosensor that may someday be used to control the symptoms of Parkinson's disease. According to researchers:
If neurites in the brain can be manipulated properly, we can control symptoms of the disease. We can stop tremors, and patients can live relatively normal lives."
The loss of dopamine in the substantia nigra causes the nerve cells that control movements to fire excessively creating the symptoms of Parkinson's. These biosensors could be used to track chemical levels in the brain and possibly even stimulate cell growth in specific regions of the brain.
There is even the possibility of biosensors in the brain sending data to sensors and devices external to the body that could help in controlling symptoms such as tremors.
