Compressed Power Spectral Arrays plot

Dear MNE community.
Thanks a lot for having this fantastic forum
I was wondering if there is any possibility to plot Compressed Power Spectral Arrays (CSA) from specific electrodes using MNE?

CSA it’s basically a plot of various periodograms overlapped (one periodogram per epoch), considering three axes (X=frequency, Y=power spectral density, Z=epochs). You can see here an example of how does it look like

and the paper from the image ((PDF) TECHNIQUES ALTERING STATES OF CONSCIOUSNESS: PSYCHO-PHYSIOLOGICAL CORRELATES AND QUANTUM-INFORMATIONAL IMPLICATIONS) .

Thanks in advance for your time and help,
Best regards!

Hi @albertoj1107, welcome to the MNE Python forum!
The Compressed Power Spectral plot is not available in mne, the preferred way to present the frequency content of the singal changing over time is the time-frequency plot (heatmap), which you can see in this tutorial:
