Sleep chemical central to effectiveness of deep brain stimulation
Date:12/23/2007

an neurons. Astrocytes were long thought of as simple support cells, but in recent years, Nedergaard and colleagues have shown that they play an important role in a host of diseases, including epilepsy, spinal cord disease, migraine headaches, and Alzheimers disease.

The research on DBS came about as a result of a presentation Nedergaard made to colleagues about her research on astrocytes. Bakos linked her detailed description of astrocyte activity to what he sees happening in the brain when deep brain stimulation is applied. Based on Bakos experience in the operating room and with funding from the National Institute of Neurological Disorders and Stroke, Nedergaard went back to the laboratory and analyzed the effects of deep brain stimulation in a way that no one had ever before considered.

The correlation between what we see in the clinic and Dr. Nedergaard has found in the laboratory is really quite startling, said Bakos. All the credit goes to her and her team. This has been a nice interchange of information between the clinic and the laboratory, to speed a discovery that really could have an impact on patients.
