Plot Global Field Power of EEG Signals — plot

Global Field Power (Lehmann & Skrandies, 1980) is a way to quantify the amount of activity in the overall electroencephalographic signal at a given timepoint. It corresponds to the spatial standard deviation.

Usage

plot_gfp(data, cols = NULL, keep_trials = FALSE)

Arguments

data: An eeg_epochs object
cols: Condition columns from the epochs metadata to calculate GFP separately for different conditions.
keep_trials: Calculate GFP for each epoch separately, then average over epochs.

Examples

plot_gfp(demo_spatial)
#> Creating epochs based on combinations of variables: participant_id 

plot_gfp(demo_spatial, keep_trials = TRUE)

plot_gfp(demo_spatial, cols = "epoch_labels")
#> Creating epochs based on combinations of variables: participant_id epoch_labels 

plot_gfp(demo_spatial, cols = "epoch_labels", keep_trials = TRUE)
