On variability in local field potentials — data and code

Data and MATLAB analysis code (Github) accompanying the preprint "On variability in local field potentials" (bioRxiv, 2025). We empirically show that outside of evoked potentials, the across-trial variance (ATV) of the EEG or local field potential (LFP) is very highly correlated to 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 pre-processed LFP data files (.mat) for MATLAB scripts reproducing the main figures
