localisation of brain function

• What is the difference between localization and holistic theory?

  • Localization: specific functions in brain areas
  • Holistic: all parts of the brain work together
• What is lateralization in the brain?

  Certain functions are controlled by one hemisphere
• Which hemisphere controls the right side of the body?

  Left hemisphere
• Which hemisphere is responsible for language?

  Left hemisphere
• What are the functions of the frontal lobe?

  • Controls voluntary movement
  • Damage may result in loss of fine movement control
• What is the role of the parietal lobe?

  • Processes sensory information from the skin
  • Sensitivity is related to the amount of somatosensory area
• What is the function of the visual area in the occipital lobe?

  • Processes visual information from each eye
  • Damage can cause blindness in part of the visual field
• What is the function of the auditory area in the temporal lobe?

  • Analyzes speech-based information
  • Damage may produce partial hearing loss
• What is Broca's area responsible for?

  Speech production
• What happens if Broca's area is damaged?

  Causes Broca's aphasia with slow speech
• What is Wernicke's area responsible for?

  Language understanding
• What happens if Wernicke's area is damaged?

  Causes Wernicke's aphasia with nonsense words
