Local field potential: Difference between revisions

{{Confusing|date=September 2008}}

A '''local field potential''' (LFP) is a particular class of [[electrophysiological]] signals, which is dominated by the electrical current flowing from all nearby [[dendritic]] [[Chemical synapse|synaptic activity]] within a volume of [[Biological tissue|tissue]]. A voltage is produced by the summed synaptic current flowing across 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]].
