In vivo recordings of network activity using local field potentials and single units in movement and network pathophysiology

Abstract

This chapter introduces basic and some advanced methods for recording, analyzing, and comparing local network electrophysiological activity in rodents and primates. Attention will be paid to the acquisition of network signals that consider the local field potentials (LFPs) and single-unit and multiunit activity. Analysis methods for extracting main features from LFP signals, their frequency, power, and coherence will be discussed, as well as the relation of unit activity with the LFPs. The relationship with movement and behavior will be developed, and so will the relation of these measures with network activity in specific pathologies of the local networks.
