• Communication may be more important process to study than localisation.

  Research suggests that what might be more important to study is how brain areas communicate with each other, rather than which specific brain regions control a particular response

  Dejerine - reported a case in which the ability to read was lost through damage to the connection between the visual cortex and Wernickes area. Suggesting functions were controlled by communication between different brain areas.
• Alphasia studies

  Alphasia studies demonstrate that these brain regions are important in the production and comprehension of of language suggesting that language is localised.

  Expressive (Broca's) alphasia is an impaired ability to produce language, this is produced by damage to the Broca area.

  Receptive (Wernicke) alphasia is an impaired ability to understand language. This is usually the result of damage to Wernickes area.
• Brain scans evidence support

  Peterson et al used brain scans to demonstrate how wernickes area was active during a listening task and Broca area was active during a reading task. Suggesting these areas have different functions supporting localisation.
• Plasticity goes against localisation

  When brain becomes damaged through illness and a particular function has been lost, the rest of the brain appears to reorganise itself in an attempt to recover lost functions.
