The local field potential (LFP) is the electric potential in the extracellular medium around neurons. The LFP is signal available in many recording configurations, ranging from single-electrode recordings to multielectrode arrays. The LFP has specific spatial and temporal properties and also depends on the brain state. Different classes of models are used to model the LFP.

Detailed Description


The local field potential (LFP) is the electric potential in the extracellular space around neurons and can be recorded using different types of microelectrodes (metal, silicon, or glass micropipettes). These characteristics differ from the electroencephalogram (EEG), which is recorded at the surface of the scalp with macro-electrodes. It was shown that the LFP samples relatively localized populations of neurons, as these signals can be very different for electrodes separated by 1 mm (Destexhe et al. 1999) or even by a few hundred microns (Katzner et al. 2009).
