"The Brain's Role in Perceiving Continuity Illusions"

A study reveals the role of the superior colliculus (SC) in the brain's transition from perceiving rapid flashes as static to continuous motion, shedding light on the continuity illusion. By employing fMRI, behavioral experiments, and electrophysiological recordings, researchers found that the SC's response changes with the frequency of visual stimuli, playing a key role in the continuity illusion. The findings not only enhance our understanding of visual perception but also open new avenues for assessing and treating visual impairments.
