چکیده انگلیسی
Microelectrode recordings were taken from the STN during surgery and neuronal activity was analyzed offline. Spectral characteristics were calculated. Clinical outcomes were evaluated pre- and post-STN DBS implantation using the Unified Parkinson's Disease Rating Scale (UPDRS III). The position of optimal electrode contacts was assessed by postoperative magnetic resonance imaging (MRI) and was compared to the location of oscillatory activity within the STN as well as its dorsal margin (where STN neuronal activity was first detected). Of the total 188 neurons obtained, 51 (27.1%) neurons showed significant oscillatory activity. Of those, 47 (92.2%) were localized in the dorsal portion of the STN. Furthermore, there was no significant difference between the averaged coordinates of the position of 40 optimal contacts and the coordinates of the dorsal margin of the STN. The data indicate that the positions of the best contacts correlate with the locations of the oscillatory neurons supporting the prediction that stimulation of the dorsolateral oscillatory region leads to an effective clinical outcome for STN DBS surgery.
