Mayo Clinic creates tool to track real-time chemical changes in brain
Date:7/15/2012

ROCHESTER, Minn. -- Mayo Clinic researchers have found a novel way to monitor real-time chemical changes in the brains of patients undergoing deep brain stimulation (DBS). The groundbreaking insight will help physicians more effectively use DBS to treat brain disorders such as Parkinson's disease, depression and Tourette syndrome. The findings are published in the journal Mayo Clinic Proceedings.

Journalists: For multimedia resources including video of a tremor patient undergoing DBS, visit the Mayo Clinic News Network.

Researchers hope to use the discovery to create a DBS system that can instantly respond to chemical changes in the brain. Parkinson's, Tourette syndrome and depression all involve a surplus or deficiency of neurochemicals in the brain. The idea is to monitor those neurochemicals and adjust them to appropriate levels.

"We can learn what neurochemicals can be released by DBS, neurochemical stimulation, or other stimulation. We can basically learn how the brain works," says author Su-Youne Chang, Ph.D., of the Mayo Clinic Neurosurgery Department. As researchers better understand how the brain works, they can predict changes, and respond before those changes disrupt brain functioning.

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 sens
