  • The brain
    • Central core- regulates primitive, involuntary behaviours
      • Hypothalamus- regulates eating, drinking and sexual behaviours
      • Endocrine system-for homeostasis
    • Limbic system- controls emotions
      • Hippocampus- important in memory. 'HM' is an example of what happens when this doesn't operate
    • Cerebrum- regulates higher intellectual processes. Composed of right and left hemispheres connected by a bundle of fibres- corpus callosum- which enables messages to be conveyed across hemispheres
      • Frontal lobe- our consciousness
      • Parietal lobe- location for sensory and motor movements
        • Motor area- controls voluntary movements- movements on right hemisphere controlled by left, vice versa. Damage= impaired movements
        • Somatosensory area- responds to sensory inputs (taste etc.) and sense of body movement. Amount of area associated with a particular part is related to its use and sensitivity
      • Temporal lobe- location for auditory ability and memory acquisition
        • Auditory area- responsible for analysis of speech- based info. Hold Wernicke's area- those struggling with language comprehension have Wernicke's aphasia
      • Occipital lobe- location for vision
        • Visual area- damage to the left hemisphere can produce loss of vision in the right side of our environment, and damage to the left optic nerve can affect the left eye
