Hemispheric Lateralization

It is generally well-known that the human brain is made up of two symmetric hemispheres, and these are joined by the corpus callosum, fibers that send information between the two hemispheres. There is some degree of specialization in the brain, with different areas specialized for processing particular forms of information. In particular, each hemisphere of the brain tends to process different types of information. For example, the left hemisphere has greater specialization for the processing of many aspects of language (e.g., reading, speech production), whereas the right hemisphere is more specialized for processing facial information (e.g., identity, emotional expression).
