Summary

Microelectrode recordings allow for the simultaneous quantification of the activity of small neuronal ensembles (multi-unit activity, MUA) and Local Field Potentials (LFPs). So far it is still unclear to what extent MUA (>500 Hz) contributes to the generation of the LFP (<500 Hz). It has been proposed that the relation between these different scales varies depending on the underlying neuronal morphology, the synaptic distribution and the correlation of synaptic activity.
