EKG
EMG
EEG
action potentials
LFPs
EKG signal recorded with Ag/AgCl electrodes on the chest:
EMG signal recorded with Ag/AgCl electrodes over bicep during
two brief muscle contractions:
EEG signal with 10-Hz alpha waves recorded from occipital region (O1-O2).  
Subject's eyes were closed initially, then opened at time zero, suppressing
the alpha waves:
Several time-aligned cortical action potentials recorded extracellularly
using a MEMS microelectrode array:
Extracellular cortical recording showing both action potentials and
local field potentials (LFPs), from a MEMS microelectrode array:
