Illusory contours

Illusory contours forming circles. This illusion demonstrates the false perception of areas of increased brightness. Lines are apparently joined to bright circles. In fact no such circles exist. It is still a source of some debate whether this effect is due to the brains attempts to interpolate fragmentary information and infer boundaries, or to the visual cortex pre-processing information before it reaches the brain

EDITORS COMMENTS
This print from Science Photo Library showcases the mesmerizing world of illusory contours. In this optical illusion, circles seemingly form through a clever trickery of our visual perception. The image challenges our understanding of boundaries and brightness as lines appear to be connected to bright circles that do not actually exist. The ambiguity presented in this panoramic view raises intriguing questions about how our brains process visual information. Scientists are still debating whether this phenomenon occurs due to the brain's attempt to fill in missing details and infer boundaries or if it is a result of pre-processing by the visual cortex before reaching conscious awareness. As we delve into the realm of neuroscience and psychology, illusions like these remind us that what we see may not always reflect reality accurately. Our vision can be easily deceived, emphasizing the intricate relationship between our eyes and mind. With its round shapes and illusory contours, this photograph serves as a reminder that appearances can indeed be deceiving. It highlights the magnitude of human perception's vulnerability to manipulation, inviting us to explore further into the fascinating world where science meets trickery.
