This is an introductory text to the neurophysiology of the senses and communication. The study of the sensory systems of humans and other animals is closely linked to communication. Combining the two subject areas in one volume provides an integrated approach to the senses, drawing on both neuroanatomy and neurophysiology to provide a picture of the structure and function of the senses. Understanding how the sensations provided by receptors are perceived within the brain is well illustrated by the example of hearing and perception of speech in humans. Animal behaviour reminds us that our sensory view of the world is not the same as all other animals. Different species have different "windows" on their world, giving each a partial view of the environment as a whole.
