Another example of the brain ‘adding’ information is the Kaniza square illusion. For example, in the image below, people often perceive a black square on top of four white circles. Instead, this image could be easily seen as four white ‘pacman’ shapes. Yet, we are more likely to perceive the square shape. This effect is known as the perception of illusory contours, and is something of interest throughout this project.
Something that excites me about studying the visual system is that much of what we experience when seeing is created internally. For example, the colours that we see do not exist out there in the world, but are generated by our brain. Our brain cells convert light into an electrical signal that we interpret as colour. In a sense, the world ‘out there’ is actually colourless. Continue reading
I’m very excited to begin this Synapse residency, generously supported by the Australian Network for Arts and Technology (ANAT). This residency is a collaboration between myself and Prof Ted Maddess at the department of Neuroscience at the John Curtin School of Medical Research. The project is titled Abstract Digital: Exploring the Art and Science of Visual Perception. Continue reading
