Spectral power, but not phase connectivity, decodes the subanaesthetic ketamine state from surface EEG: the role of between-subject transferability
Hannes Schätzle, Frederic von Wegner
Abstract Subanaesthetic ketamine alters the content of consciousness while leaving responsiveness intact. We asked whether this state can be decoded from single eyes-closed EEG epochs, and how spectral power and phase-based connectivity compare when used as features. Re-analysing openly available 62-channel EEG from ten participants (awake versus subanaesthetic ketamine), we trained classifiers...
