Visualization and frequency analysis of electrophysiological data. (Left) Raw ECoG and DBS signals across multiple channels are normalized for visualization. Dashed lines indicate the start of the trials. (Right) Power spectral density (PSD) plot for the RDBS1 channel during a rest trial, displaying power distribution across frequencies from 2 to 100 Hz.
