Abstract :
Larsen and Lai1 present an empirical proof that Walsh spectral features classify EEG data in much the same way as the Fourier spectral analysis,1 despite contradictory results reported in [1]. It is the purpose of this comment to present additional information that may explain this discrepancy.
