Optical illusions in the MindWorks exhibition on Floor 2 at Glasgow Science Centre

MindWorks brings together a collection of phenomena to illustrate different kinds of illusions and their causes. Some illusions have physiological causes. They are the result of disturbances in the signals sent from your senses to your brain.

Others are about cognitive processes. This is how your brain makes sense of sensory signals using rules and past knowledge, though it sometimes gets it wrong.

In other words, all illusions are caused by flaws in either the way our body or our mind works. Scientists study how we respond to illusions to help us understand how our bodies and minds work together. This makes the things you experience today useful scientific tools as well as being a great deal of fun!

You can try out a cool illusion back at home. Find out more about our Coloured Curves science bite.
