Saccadic Masking: How Your Brain Hides Reality's Gaps
Original: Your visual cortex temporarily cuts video transmission during eye saccades (saccadic masking) so your skull's vibration
Scientists and science communicators are highlighting saccadic masking, the process by which the visual cortex suppresses perception during rapid eye movements. Because the eyes jump several times a second, the brain blanks out these moments to prevent blurring and motion sickness, then fills the gaps. The takeaway circulating widely is that consciousness never experiences a raw feed of physical reality, but rather a predictive rendering generated by the brain.
Why now: The counterintuitive idea that our perception is a constructed simulation rather than direct reality is capturing attention.
