Oscillatory local field potentials recorded from the subthalamic nucleus of the alert rat.
Hitherto, high-frequency local field potential oscillations in the upper gamma frequency band (40-80 Hz) have been recorded only from the region of subthalamic nucleus (STN) in parkinsonian patients treated with levodopa. Here we show that local field potentials recorded from the STN in the healthy alert rat also have a spectral peak in the upper gamma band (mean 53 Hz, range 46-70 Hz). The pow...
متن کاملDecoding gripping force based on local field potentials recorded from subthalamic nucleus in humans
The basal ganglia are known to be involved in the planning, execution and control of gripping force and movement vigour. Here we aim to define the nature of the basal ganglia control signal for force and to decode gripping force based on local field potential (LFP) activities recorded from the subthalamic nucleus (STN) in patients with deep brain stimulation (DBS) electrodes. We found that STN ...

متن کاملDirectional Local Field Potentials: A Tool to Optimize Deep Brain Stimulation
BACKGROUND Although recently introduced directional DBS leads provide control of the stimulation field, programing is time-consuming. OBJECTIVES Here, we validate local field potentials recorded from directional contacts as a predictor of the most efficient contacts for stimulation in patients with PD. METHODS Intraoperative local field potentials were recorded from directional contacts in ...
متن کاملThe impact of bilateral subthalamic deep brain stimulation on long-latency event-related potentials.
The analysis of long-latency event-related potentials (ERPs) is of importance in the evaluation of certain cognitive functions and in following their subsequent changes. The aim of the present study was to investigate whether deep brain stimulation (DBS) itself can cause changes in the configuration of the ERPs. Using a standard oddball auditory paradigm, we elicited auditory cognitive ERPs in ...
