  • 8.3 The Brain
    • Cerebral Hemispheres
      • Frontal Lobe
        • Higher functions
        • Decision making
        • Reasoning
        • Planning
        • Consciousness of emotions
      • Parietal Lobe
        • Types of recognition and memory
        • Orientation
        • Movement
        • Sensation
        • Calculation
      • Occipital Lobe
        • Vision
      • Temporal
        • Auditory information
        • Involved in memory
      • Thalamus
        • Routes all incoming sensory info to correct part of the brain
      • Hypothalamus
        • Thermoregulatory centre
        • Sleep centre
        • Thirst and hunger centre
        • Endorcrine gland
      • Hippocampus
        • Long term memory
      • Basal ganglia
        • Collection of neurones
    • Cerebellum and Brain Stem
      • Medulla Oblongata
        • Regulates body processes that we don't consciously control
        • Breathing
      • Cerebellum
        • Balance
        • Coordinates movement
        • Receives info from motor cortex
      • Midbrain
        • Relays info to cerebral hemispheres
    • Studies of individuals
      • Phineas Gage
        • 3.5 foot long iron bar through his head
        • Emotions affected
        • Unable to complete plans for the future
        • Severed connections between midbrain and frontal lobe
      • Lincoln Holmes
        • Recognition impossible
        • Temporal lobe affected
    • Strokes
      • Problems with speech, understanding, reading, and writing
      • Neural plasticity
        • Potential of neurones to change in structure and function
    • Brain Imaging
      • CT Scans
        • Overcomes limits of X-rays
        • Narrow beamed x-rays used
        • Thin slice of brain imaged
      • MRI
        • Nuclei of atoms line up in a magnetic field
        • Different tissues respond differently to the magnetic field
        • Examines tissues in small sections
      • fMRI
