Changes in brain activity, specifically electroencephalography (EEG) microstates and Omega complexity, precede shifts in illusory motion perception. These sub-second EEG changes may reflect fluctuations in arousal levels during perception shifts.

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Psychophysics

Background:

  • Multistable perception involves subjective shifts in interpreting ambiguous stimuli.
  • Electroencephalography (EEG) microstates and spatial Omega complexity are sensitive measures of brain dynamics.

Purpose of the Study:

  • To investigate transient changes in EEG microstates and spatial Omega complexity preceding perceptual shifts in illusory motion.
  • To explore the relationship between these electrophysiological markers and arousal fluctuations during ambiguous perception.

Main Methods:

  • Recorded 21-channel EEG from 13 healthy subjects viewing an ambiguous, alternating dot pattern inducing illusory motion.
  • Compared EEG microstates and Omega complexity during stable perception (baseline) with periods preceding perceived changes in motion direction.

Related Experiment Videos

Main Results:

  • A decrease in Omega complexity and altered EEG microstate probabilities were observed approximately 750 ms before perceived motion direction changes.
  • An increase in Omega complexity and reversal of microstate deviations occurred around 300 ms before the perceptual shift.
  • These sub-second changes in EEG dynamics were linked to fluctuations in arousal.

Conclusions:

  • Sub-second EEG changes in microstates and Omega complexity are associated with perceptual transitions in illusory motion.
  • These findings suggest that discontinuities in illusory motion perception may occur during brief dips in arousal, with subsequent illusion reconstruction coinciding with relative over-arousal.
