The video explores how optical illusions trick the brain by exploiting its shortcuts in processing visual information. It covers various illusions, including persistence of vision, afterimages, motion aftereffect, Shepherd's tables, bi-stable illusions, checkered square, Hermann grid, and mirages. Each illusion demonstrates how the brain interprets visual cues, often leading to misperceptions. The video highlights the complexity of visual processing and the interplay between neuroscience, psychology, and physics in creating these illusions.
