Synaesthesia (“union of the senses”) is a neurological phenomenon in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. In one common form of synaesthesia, for instance, letters or numbers are perceived as inherently coloured. People who report such experiences are known as synaesthetes. This book is both a personal and a semi-scientific research into synaesthesia.
