On variability in local field potentials

Data (and MATLAB analysis scripts, via GitHub) for generating the main figures of the paper "On variability in local field potentials". We empirically demonstrate that, outside of evoked potentials, the across-trial variance (ATV) of the EEG or local field potential (LFP) is highly correlated with the intra-trial variance (ITV), which corresponds to the well-known power metric. We propose that LFP power, rather than the raw LFP signal, should be considered for putative changes in its variability. LFP power variability is quantified as the CV of the power. This repository contains .mat files for MATLAB scripts reproducing the main figures.
