Visual perception changes, even without movement, alter brain activity. This study links visual percept shifts during binocular rivalry to changes in sensorimotor mu rhythm, suggesting visuomotor network involvement.

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Visual Perception

Background:

  • The visual and sensorimotor systems exhibit functional coupling, evident in behaviors like manual object exploration.
  • Binocular rivalry presents a unique paradigm to study interactions between visual perception and sensorimotor processing.

Purpose of the Study:

  • To investigate the relationship between changes in visual perception during binocular rivalry and sensorimotor mu rhythm activity.
  • To determine if altered visual percepts, independent of motor responses, modulate neural activity in the sensorimotor system.

Main Methods:

  • Human volunteers underwent whole-scalp neuromagnetometry to monitor sensorimotor mu rhythm.
  • Participants viewed competing gratings under binocular rivalry conditions, with controlled visual motion stimuli.

  • Mu rhythm levels were analyzed in relation to perceptual dominance shifts.

    • Main Results:

    • A transient increase (10-15%) in the postcentral 8- to 15-Hz mu rhythm was observed approximately 450 ms after movement onset, coinciding with a shift in visual dominance.
    • Mu rhythm enhancement also occurred when the dominant stimulus disappeared, irrespective of the rivalry stimulus.
    • Visual motion without a perceptual change elicited only minor effects on the mu rhythm.

    Conclusions:

    • Changes in visual perception, even without overt motor actions, are associated with modified activity in the postcentral gyrus.
    • These findings suggest potential visuohaptic interactions or the involvement of cortical networks underlying visually guided movements.
