4 lobes

• frontal lobe


  larges of the brain lobes

  latest to develop

  the executive brain

  Guiding behaviour

  • Reward, personality insight, foresight 
  • The orbital portion of the prefrontal cortex is important in the appropriate switching between mental sets and the regulation of emotion 
  • Broca's speech area 
  • The motor mechanisms of speech formulation: primarily involving the coordination and control of muscles that produce speech 
  • Motor 
  • Primary motor cortex, where all parts of the body are represented, the premotor and supplementary motor areas
• temporal lobe


  Language processing - Wernicke's area 

  • Crucial for language comprehension and understanding spoken/written language 
  • Essential role in reading skills 
  • Long term memory 
  • Primary auditory cortex 
  • Para hippocampal gyrus 
  • Supports language comprehension and communication by providing contextual information 
  • Involved in learning and contextual memory, helps recalling info 
• occipital lobe


  Vision - one of the most complex senses

  • Primary visual cortex 
  • Located in and around the calcarine fissure 
• parietal lobe


  Association cortex integrates sensory information from multiple modalities 

  • Primary somatosensory cortex - tactile perception
  • Integrating and processing sensory information from the body 
  • Cortical association area 
  • Inferior parietal gyrus integrates and processes sensory information from multiple modalities
  • Spatial processing 
  • Superior parietal gyrus is concerned with spatial orientations and body image
