Lobes of the Brain

  1. What is the frontal lobe associated with?
    Involved with cognitive processes such as judging, planning and initiative, aspects of personality and emotions and voluntary muscle movements.
  2. What is the primary cortex of the frontal lobe and what are its functions?
    • Primary motor cortex
    • Involved in controlling voluntary body movement through its control of muscles
  3. Name and function:
    Image Upload 1
    • Broca's area, found in the left frontal lobe
    • Production of clear, articulate speech
    • Vital for the proper grammatical structure of sentences
    • Coordinates the movements of the muscles required for speech
  4. Name and function:

    • Wernicke's area
    • Vital role in interpreting sound and speech comprehension. Locating and retrieves words from memory.
  5. Name:

    • A. Broca's area
    • B. Primary motor cortex
    • C. Primary somatic sensory Cortex
    • D. Somatic sensory association area (parietal lobe)
    • E. Wernicke's Area
    • F. Primary visual cortex
  6. What lobe does this represent?
    Image Upload 4
    Frontal lobe: complexity of movement
  7. What are the parietal lobes responsible for?
    • Perception of own body and where things are located in immediate surroundings
    • Right: perception of three-dimensional shapes and designs. Awareness of space and location of objects in environment
    • left: mental arithmetic, reading and writing
  8. What is the somatosensory cortex responsible for?
    Responsible for processing bodily sensations such as pain, temperature, touch & pressure
  9. What are the temporal lobes responsible for?
    • Responsible for processing auditory information. Remembering faces, memory
    • Primary auditory cortex: analyses sensations perceived through the ears eg. speech, music
  10. Describe the occipital lobes
    • Concerned with vision. Organises visual stimuli into more complex forms to enable interpretation
    • Primary visual cortex: Processes different types of visual stimuli
  11. What is Aphasia?
    Language difficulties such as writing, reading and speaking due to damage to the brain
  12. What is Wernicke's aphasia?
    • aka Receptive aphasia
    • The individual has trouble understanding written and spoken language.
    • Speech is fluent but meaningless
    • Partial or complete loss of ability to recall names (anomia)
  13. What is Broca's aphasia?
    • Caused by damage to Broca's area
    • aka Expressive aphasia
    • Difficulties speaking, non fluent
    • Speech lacks grammar and syntax
    • Difficulty with writing
    • Partial or complete loss of ability to recall names (anomia)
    • Can usually comprehend speech
  14. What is the left hemisphere responsible for?

  15. What is the right hemisphere responsible for?

  16. What is spatial neglect?
    • A disorder in which an individual ignores stimuli on one side of their body
    • Occurs after brain injury (caused by stroke or brain injury) and relates to visual stimuli.
    • ‘blind’; the eyes function normally however
    • the brain is unable to process visual stimuli normally.
