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. A voltage is produced by the summed synaptic current flowing across the resistance of the local extracellular space. In this situation, "potential" refers to electrical potential, or voltage, and particularly to voltage recorded with a very small electrode embedded within neuronal tissue, typically in the brain of an anesthetized animal or within a thin slice of brain tissue maintained in vitro.

Famous quotes containing the words local, field and/or potential:
“Reporters for tabloid newspapers beat a path to the park entrance each summer when the national convention of nudists is held, but the cult’s requirement that visitors disrobe is an obstacle to complete coverage of nudist news.
