Synaesthesia is a joining together of sensations that are normally experienced separately. Studying synaesthesia may help us to understand how the brain segregates and integrates different sensations and thoughts. The Synaesthesia research group at the University of Sussex look at a wide variety of topics related to synaesthesia, encompassing research on both adults and children, as well as the potential application of synaesthesia research. Our website is designed to help you discover more about synaesthesia, and to invite you to take part in our research. We hope you will find it useful! If you would like to tell us about your synaesthesia, please email us.
