Why does rotating tilted lines Illusion rotate?

A new motion illusion: the Rotating-Tilted-Lines illusion.

Introduction Visual illusions are not just entertainingöthey also are non-invasive means for investigating human brain mechanisms.While they show us where our visual system fails, they can also tell us how it works. Therefore, we introduce here a new motion illusion that could represent the simplest pattern that elicits illusory motion through self-motion. It may be instrumental for future rese...

The riddle of the Rotating-Tilted-Lines illusion.

Gori and Hamburger (2006, Perception 35 853-857) devised a new visual illusion of relative motion elicited by the observer's motion. We propose that the systematic error of direction discrimination found by Lorenceau et al (1993, Vision Research 33 1207 - 1217) can explain this illusion. The neural correlate of such a systematic error with respect to the two types of neurons in the primary visu...

Why Does the Liquid Crystal Rotate?

Does the Kai clock rotate?

suggests that an ancient circadian clock rotates much like a hand on an analogue clock. His analysis of cyanobacterial clock protein structures reveals a similarity with the F 1-ATPase rotary motor. The cyanobacterial clock is controlled by the KaiA, KaiB, and KaiC proteins, which form a complex at night that falls apart in the day. Mutations causing more stable complexes correspond to a longer...

Understanding the Rotating Snakes illusion

This paper explores potential mechanisms underlying Rotating Snakes a piece of Op-Art by Kitaoka evoking a striking apparent motion illusion. The Op-Art is based on an illusion developed by Kitaoka & Ashida (2003) and is similar to previous illusions developed by Fraser & Wilcox (1979), Faubert & Herbert (1998) and Naor-Raz & Sekuler (2000). The subsequent illusions, including Rotating Snakes a...
