Wavelets and switching in bistable visual perception: Comment on "Wavelet analysis in biomedical research: A versatile tool for multiscale signal characterization and functional connectivity analysis" by Kralj et al․

This Comment highlights bistable perception as a link between wavelet-based signal characterization and functional connectivity. Prior frequency-tagged Necker-cube experiments used wavelet power to identify candidate perceptual switches and assess selective attention, while complementary EEG studies examined network organization. Integrating time-local dominance estimates with dynamic connectivity could clarify how network reconfiguration relates to switching. Such analyses require behavioral validation, consideration of wavelet resolution, and separation of connectivity from power changes. Frequency tags remain indirect perceptual markers, not intrinsic brain rhythms.
