The Brain lobes

• How many lobes does the brain have?

  4 lobes in each hemispheres.

  
  

  Frontal lobe

  Parietal lobe

  Temporal lobe

  Occipital lobe
• Frontal Lobe


  Largest lobe

  
  

  Wrapped by the Cerebral cortex = 3mm thick and convolated (folds)

  
  

  Functions:

  body movement

  language

  planning

  
  

  Consists of Broca's area = speech production

  Amygalda = Emotions

  Prefrontal cortex = Interpret meaning of language
• Parietal lobe


  Occupies the primary somatosensory cortex = touch, pressure, temperature, and pain

  
  

  Contraleteral organisation = each side is processedl by the opposite hemisphere
• Temporal lobe


  Procces the auditory information

  e.g. music and speech

  
  

  Primary auditory cortex = located upper part of temperal lobe
• Occipatal lobe


  Located on the rear end of the brain

  
  

  Proccess info from both sided of retina

  left side = left occipital lobe

  Right Side = Right occipital lobe

  
  

  Contains primary visual cortex = procces of reciveing info from eyes

  
  

  Association area = communication between motor and sensory areas + higher order mental proccessing
• Broca's area


  The association area of the frontal lobe

  
  

  Coodinates speech movement
• Amygalda


  Located in the frontal lobe

  
  

  Within the limbic system

  
  

  Responsible for emotioal responses
• Prefrontal cortex


  Located in the frontal lobe, behind the forehead

  
  

  Responsible for planning, emotion regulation and cognitive function (memory + focus)
• Left Hemisphere

  Controls Right

  Language and Speech
• Right Hemisphere

  Controls Left

  Controls attention + memory
