  1. Limbic system
    • Thalamus: conveys sensory info to cortex
    • Hypothalamus: overseas endocrine and autonomic nervous system
    • Amygdala: regulates arousal and fear
    • Hippocampus: processes memory for spatial locations
  2. cerebellum
    controls balance and coordinated movement
  3. brain stem
    • mid brain: tracks visual stimuli and reflexes trigered by sound
    • pons: conveys info between cortex and cerrebelum
    • medulla: regulates breathing and heartbeats
  4. wernicke's area
    broca's area
    primary sensory cortex motor cortex
    • Wernickes: interprets spoken and written language. Temporal lobe.
    • Broca's: vital for formation of speech. frontal lobe
    • PSC: parietal lobe, receives data about sensations in skin, muscles and joints
    • Motor cortex: generates signals responsible for voluntary movements
  5. basal ganglia:
    limbic system
    • basal: structures in the forebrain that help control movement
    • limbic: emotional centre of brain that also plays a role in smell, motivation and memory
  6. CT, mri, pet, fmri
    • CT: 3d image of brain
    • MRI: uses magnetic fields to indirectly visualise brain structure
    • PET: measures uptake of radioactive glucose molecules, picture of metabolic activity in brain
    • fmri: magnetic field to visualise changes in blood oxygen levels due to brain activity
