brain anatomy

  1. cerebral cortex
    • gray matter
    • 2 hemispheres
  2. L hemisphere
    • sequential analysis
    • symbolic info
    • memory in language format
  3. R Hemisphere
    • holistic: multi-sensory input
    • visual spatial skills
    • memory in auditory, visual and spatial format
  4. corpus callosum
    • communication b/w hemi
    • split brain syndrome
  5. frontal lobe
    • cognition and memory:
    • prefrontal area: concentrate, judgement, inhibition, personality and emotional traits
    • movement
    • brodman's: voluntary motor activity
    • premotor cortex: storage of motor and voluntary patterns
    • language: motor speech
  6. parietal lobe
    • sensory input
    • body orientation
    • somatic area
  7. occipital lobe
    • visual reception area
    • visual interpretation
  8. temperal lobe
    • auditory
    • expressed behaviour
    • language
    • memory
  9. limbic system
    • olfactory
    • amygdala
    • hippocampus
    • limbic: emotions
    • hypothalamus
  10. basal ganglia
    • subcortical gray matter nuclei
    • voluntary movement
    • balance
    • postural reflexes
    • extrapyramidal system: automatic movement
  11. --plegia
  12. --paresis
  13. aphasia
    total or partial loss of the ability to use or understand language; usually caused by stroke, brain disease, or injury.
  14. chorea
    Chorea is an abnormal involuntary movement disorder, one of a group of neurological disorders called dyskinesias, which are caused by overactivity of the neurotransmitter dopamine in the areas of the brain that control movement. Chorea is characterized by brief, irregular contractions that are not repetitive or rhythmic, but appear to flow from one muscle to the next.
  15. Parkinsons
    • Parkinson’s is a neurodegenerative disease. Movement is normally controlled by dopamine, a chemical that carries signals between the nerves in the brain. When cells that normally produce dopamine die, the symptoms of Parkinson’s appear.
    • Tremor
    • Slowness and stiffness
    • Impaired balance
    • Rigidity of the muscles
