Hypnotic Zigzag Spiral Optical Illusion Sphere - Visual Perception Study #224588 (License: Personal Use)

This high-contrast monochrome image features a spherical surface covered in concentric zigzag bands that radiate from the center, producing a powerful illusory rotation known as the peripheral drift illusion. The alternating black and white segments exploit human visual processing, particularly motion-sensitive neurons in the retina and V5/MT cortex, tricking the brain into perceiving continuous motion. Such illusions are widely used in cognitive science to study perception, attention, and neural adaptation.
