Online analysis of local field potentials for seizure detection in freely moving rats
Objective(s): Seizure detection during online recording of electrophysiological parameters is very important in epileptic patients. In the present study, online analysis of field potential recordings was used for detecting spontaneous seizures in epileptic animals.Materials and Methods: Epilepsy was induced in rats by pilocarpine injecti...
متن کاملReliability of directional information in unsorted spikes and local field potentials recorded in human motor cortex.
OBJECTIVE Action potentials and local field potentials (LFPs) recorded in primary motor cortex contain information about the direction of movement. LFPs are assumed to be more robust to signal instabilities than action potentials, which makes LFPs, along with action potentials, a promising signal source for brain-computer interface applications. Still, relatively little research has directly co...
متن کاملLocal field potentials get funny
The local field potential (LFP) is widely used experimentally to index cortical activity and information processing. Classic studies using recordings of LFPs include the first demonstration of long-term potentiation (Bliss & Lomo, 1973) and descriptions of oscillatory brain states (Buzsaki & Draguhn, 2004), while more recent applications extend as far as control of brain–machine interfaces by i...
متن کاملMeasuring fundamental frequencies in local field potentials.
Neural processes display rhythmic oscillations in local field potentials; identification of their characteristic frequencies is complicated due to their highly non-stationary nature. A simple technique, combining Fourier transforms and correlation coefficients yields unambiguous determinations of the frequencies without a priori filtering. This procedure also provides quantitative information c...
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 ...
