Distribution of signal (open bars) and noise (dark bars) in extracellular action potential (EAP) data recorded from single units with Thomas tetrodes in visual cortex (N=61). Noise level is defined by per-channel RMS amplitude; the mean (range) was 21 (12–35) µV. Signal level is defined by the spatial minimum of EAP peak amplitude on the tetrode channel that registered the largest peak; the mean (range) was 91 (25–313) µV
