Large-scale, high-resolution electrophysiological imaging of field potentials in brain slices with microelectronic multielectrode arrays
Multielectrode arrays (MEAs) are extensively used for electrophysiological studies on brain slices, but the spatial resolution and field of recording of conventional arrays are limited by the low number of electrodes available. Here, we present a large-scale array recording simultaneously from 4096 electrodes used to study propagating spontaneous and evoked network activity in acute murine cort...
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 کاملClinical Outcome and Characterization of Local Field Potentials in Holmes Tremor Treated with Pallidal Deep Brain Stimulation
BACKGROUND Holmes tremor (HT) is an irregular, low-frequency rest tremor associated with prominent action and postural tremors. Currently, the most effective stereotactic target and neurophysiologic characterization of HT, specifically local field potentials (LFPs) are uncertain. We present the outcome, intraoperative neurophysiologic analysis with characterization of LFPs in a patient managed ...
متن کاملO10: Deep Brain Stimulation and Psychiatry
The use of deep brain stimulation in psychiatric disorders has received great interest owing to the small risk of the operation, the reversible nature of the technique, and the possibility of optimizing treatment postoperatively. Currently deep brain stimulation in psychiatry is investigated for obsessive-compulsive disorder, Gilles de la Tourette’s syndrome and major depression. This presentat...
متن کاملβ-Band Peak in Local Field Potentials as a Marker of Clinical Improvement in Parkinson’s Disease after Deep Brain Stimulation
Although locating the stimulation contact in Deep Brain Stimulation (DBS) requires a sub-mm-precision, it remains a trial-and-error, patient-specific procedure that is usually the main cause of post-operational side-effects. In this work, we used microelectrode recordings from Parkinson’s disease (PD) patients, acquired at the Neurosurgery Clinic, Evangelismos Hospital, Athens, Greece, to relat...
