Local Field Potential

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:

    Back now to autumn, leaving the ended husk
    Of summer that brought them here for Show Saturday
    The men with hunters, dog-breeding wool-defined women,
    Children all saddle-swank, mugfaced middleaged wives
    Glaring at jellies, husbands on leave from the garden
    Watchful as weasels, car-tuning curt-haired sons
    Back now, all of them, to their local lives....
    Philip Larkin (1922–1986)

    Father calls me William, sister calls me Will,
    Mother calls me Willie, but the fellers call me Bill!
    —Eugene Field (1850–1895)

    Democracy is timelessly human, and timelessness always implies a certain amount of potential youthfulness.
    Thomas Mann (1875–1955)
