The brain

Abstract

Perception involves the active searching for and processing of information. Although we are traditionally regarded as possessing five separate senses, these senses are better thought of as information-processing systems sharing the same basic principles. In the last century, scientists believed that our brains were specialized into different areas which were responsible for different functions. To some extent they were right, and we now know a considerable amount about how specialized areas in the brain are responsible for processing different kinds of information.
