Gori and Hamburger (2006) presented the Rotating Tilted Lines Illusion (RTLI). Moving back and forth in front of this pattern makes the circle of lines appear to rotate in a clockwise and counterclockwise direction, respectively. The building blocks of the illusion are very simple: lines. This enables one to investigate the underlying mechanisms of the illusion directly. We reviewed the previous modeling works in this respect (Grossberg and Mingolla 1993; Gurnsey, Sally et al. 2002) and proposed an explanation of the illusory phenomenon based on a competition between the two types of neurons in primary visual cortex, namely end-stopped and contour cells (Pack, Livingstone et al. 2003; Yazdanbakhsh and Livingstone 2006). The illusion can be described based on the weighted average of the response of the two types of cell populations. A simple model for the integration of the two motion signals is proposed and discussed.
