Researchers Use Implants to Monitor Neuro-chemical Changes in Real Time in Patients Undergoing Deep Brain Stimulation
Researchers observed the real-time changes of the neurotransmitter adenosine in the brains of tremor patients undergoing deep brain stimulation.
Neurotransmitters such as dopamine and serotonin are chemicals that transmit signals from a neuron to a target cell across a synapse.
The team used fast scan cyclic voltammetry (FSCV) to quantify concentrations of adenosine released in patients during deep brain stimulation. The data was recorded using Wireless Instantaneous Neurotransmitter Concentration Sensing, a small wireless neurochemical sensor implanted in the patient’s brain. The sensor, combined with FSCV, scans for the neurotransmitter and translates that information onto a laptop in the operating room.
The sensor has previously identified neurotransmitters serotonin and dopamine in tests in brain tissue. This was the first time researchers used this technique in patients.
