Brain Lateralisation

Lateralization of the brain is widespread in vertebrates. Many species share a general pattern of using the right hemisphere to attend to novelty and execute rapid responses, whereas the left hemisphere is used to categorize stimuli and control responses requir- ing consideration of alternatives.
