    • 14.1: Introduction
      This page debunks the myth linking analytical thinking to the left brain and creativity to the right, highlighting that both hemispheres can perform similar functions with slight preferences. It outlines how the right hemisphere is better at processing visual duration, while language functions primarily occur in the left hemisphere. The chapter seeks to clarify the complex roles of brain lateralization.
    • 14.2: Lateralization
      This page emphasizes the bilateral symmetry of mammals and the asymmetry of their internal organs, focusing on the brain's hemispheres linked by the corpus callosum. Research by Myers and Sperry on split-brain patients shows that severing this connection leads to independent processing in each hemisphere, causing cognitive deficits.
    • 14.3: Language
      This page explores language as a key evolutionary tool for Homo sapiens, detailing its components: phonemes, morphemes, syntax, and semantics. It explains the brain regions responsible for language and the impact of damage, leading to various types of aphasia, including Wernicke’s, conduction, and global aphasia. The Wernicke-Geschwind model is mentioned for its simplification of language processing.
