Local Field Potential, Synchrony of

Encyclopedia of Computational Neuroscience

Synonyms

Coherence of local field potentials; Coupling of local field potentials; Cross-correlation of local field potentials

Definition

Synchrony of local field potentials (LFP) is a neurophysiological property that represents the correlation of activity between simultaneously recorded networks. Its measurement indicates how tightly multiple local networks are coupled. LFP synchrony indicates a potential interaction between the recorded sites and a possible mechanism to facilitate synaptic transmission and network-to-network communication.

Detailed Description

The Neural Basis of Local Field Potentials

Local field potentials (LFPs) are the integrated electrical signals recorded from a local population of neurons. Each neuron’s intracellular membrane potential provides an indication of its excitability, its readiness to fire. Using low-impedance electrodes, small intracellular synaptic voltage fluctuations from a population of cells combine together into a spatiotemporally integrated...
