plotting.plot_psd_topography

autoclean.functions.visualization.plotting.plot_psd_topography(raw, freq_bands=None, output_path=None, title='Power Spectral Density Topography', verbose=None)

Plot power spectral density topographical maps for frequency bands.

This function creates topographical maps showing the distribution of power across the scalp for different frequency bands.

Parameters:

rawmne.io.Raw

Raw EEG data to analyze.

freq_bandsdict or None, default None

Dictionary of frequency bands with format {‘band_name’: (low_freq, high_freq)}. If None, uses standard EEG bands.

output_pathstr, Path, or None, default None

Path to save the plot. If None, plot is not saved.

titlestr, default “Power Spectral Density Topography”

Title for the plot.

verbosebool or None, default None

Control verbosity of output.

Returns:

figmatplotlib.figure.Figure

The created figure object.
