Hierarchical brain dynamics supporting visual perceptual transitions
Science Advances May 8, 2026 Max Levinson, Alice Waitt, Katharina Duecker et al.
Transitions in conscious visual perception involve two distinct neural mechanisms: boundary fading in visual cortex, marked by increased excitability and reduced alpha-band activity indicating a shift in excitation-inhibition balance, and higher-order perceptual monitoring in motor cortex, reflected by decreased high-alpha and beta-band activity. Microsaccadic eye movements, which delay the illusion, selectively reset both processes. These findings support a hierarchical framework where visual and motor systems jointly shape changes in conscious experience.
