Local Field Potentials can be used to test the noise present in large neuronal networks.

Larger electrodes are sensitive only to the net activity of many cells, termed local field potentials.

It has been observed that local field potentials in cortical neurons can serve to synchronize neuronal activity.

Although the mechanism is unknown, it is hypothesized that neurons are ephaptically coupled to the frequencies of the local field potential.

Wilke, M., et al. (2006) Local field potential reflects perceptual suppression in monkey visual cortex.

Thus changes in the local field potential represent simultaneous dendritic events in cells in the open field configuration.

That is, synchronized firing patterns result in synchronised input into other cortical areas, which gives rise to large-amplitude oscillations of the local field potential.

The component of the field due to the synaptic mechanism is referred to as the local field potential (LFP).

The local field potentials of the neocortex and cerebellum oscillate coherently at (6-40 Hz) in awake behaving animals.

The local field potential, which includes both post-neuron-synaptic activity and internal neuron processing, better predicts the BOLD signal.

The cortical local field potentials (LFPs) of consciousness monkeys was recorded while they performed a precision grip task.

If numerous neurons spike in synchrony, they can give rise to oscillations in local field potentials (LFPs).

The local field potential is believed to represent the synchronised input into the observed area, as opposed to the spike data, which represents the output from the area.

In one experiment, Dr. Kennedy adapted the neurotrophic electrode to read local field potentials (LFPs).

An evoked response study of congenitally deaf kittens by Klinke et al. utilized local field potentials to measure cortical plasticity in the auditory cortex.

ECoG signals are composed of synchronized postsynaptic potentials (local field potentials), recorded directly from the exposed surface of the cortex.

Local field potentials (LFPs) are electrophysiological signals that are related to the sum of all dendritic synaptic activity within a volume of tissue.

Using depth electrodes, the local field potential gives a measure of a neural population in a sphere with a radius of 0.5-3 mm around the tip of the electrode.

Neural oscillations are observed throughout the central nervous system and at all levels, e.g., spike trains, local field potentials and large-scale oscillations which can be measured by electroencephalography.

This signal is then low-pass filtered, cut off at 300 Hz, to obtain the local field potential (LFP), that can be recorded electronically or displayed on an oscilloscope for analysis.

A local field potential (LFP) is a particular class of electrophysiological signals, which is dominated by the electrical current flowing from all nearby dendritic synaptic activity within a volume of tissue.

Authors report that the disappearance of the stimulus triggered changes in the local field potentials of all these areas, suggesting that the perception during flash suppression is reflected in large parts of the brain.

Studies of local field potentials have also shown an increase of 4-10 Hz oscillatory activity in the globus pallidus internus during myoclonic episodes and an increase of 5-7 Hz activity in dystonic muscles when compared to other primary dystonias.

Usage of this tool enables neuroscientists to perform a variety of analysis on multichannel electrophysiological data such as LFP (local field potentials), EEG, MEG, Neuronal spike times and also on spatiotemporal data such as FMRI and dynamic optical imaging data.
