(a) Block diagram for extracting the eMUA. MUA signal is obtained by bandpass filtering of a raw extracellular recording. Following full-wave rectification and low-pass filtering are carried out to estimate the eMUA signal. (b) Examples of MUA recordings and their corresponding eMUA. Arrows indicate the occurrence of spike activities.
