Light, sound, taste, and smell shape our lives dramatically, but how does this happen? How can a faraway noise elicit a joyful memory or a cry? How can the smell of cookies take you back to early childhood? These powerful stimuli exist in our environment, yet remain neutral until our brain decodes the necessary information into meaningful senses. In other words, light is transformed into vision, and sound into hearing, by the brain and the brain only. Seeing, Hearing, and Smelling the World reveals the phenomena underlying our senses, with a brief discussion of what can go wrong (for example, hearing colors or seeing sounds). This book will reacquaint readers with their senses and challenge their fundamental understanding of the amazing human mind.
