The low-frequency part of the extracellular electric signals, the local field potentials (LFP), carries information about dendritic processing in neuronal populations. However, the long-range nature of electric field makes the analysis of LFP difficult, as typically an electrode records activity of many sources. Modern multielectrodes allow for increased spatial resolution, hence also the need for effective data analysis methods which would allow to get more insight. These methods include Current Source Density (CSD) analysis and source separation methods.
