Performance monitoring local field potentials in the medial frontal cortex of primates: supplementary eye field.
We describe intracranial local field potentials (LFPs) recorded in the supplementary eye field (SEF) of macaque monkeys performing a saccade countermanding task. The most prominent feature at 90% of the sites was a negative-going polarization evoked by a contralateral visual target. At roughly 50% of sites a negative-going polarization was observed preceding saccades, but in stop signal trials ...

متن کاملOnline 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 کاملDynamics of Eye-Position Signals in the Dorsal Visual System
BACKGROUND Many visual areas of the primate brain contain signals related to the current position of the eyes in the orbit. These cortical eye-position signals are thought to underlie the transformation of retinal input-which changes with every eye movement-into a stable representation of visual space. For this coding scheme to work, such signals would need to be updated fast enough to keep up ...
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...
