  1. What is cardiocentric brain research?
    The heart controlled thoughts, emotions, and behavior

  4. What is holism?
    Every area of the brain can control all human functions

    Human functions are regulated by distinct brain regions
  6. Why did Franz Gall believe in localization?
    Phrenology: felt brain via skull and corresponded to specific personality traits
  7. Why did Karl Lashley believe in holism?
    • Law of mass action: lesion size rather than location is what matters
    • Law of equipotentiality: restatement of holism

    The mind and body are separate
  10. 2 people of dualism
    • Plato
    • Descartes
  11. What is monism?
    The mind is the result of brain functions & follows physical laws
  12. 2 people of monism
    • Da Vinci
    • Most modern brain scientists
  13. What is blindsight?
    Cannot see objects in their blind field to reach form them while remaining "unconscious" of perceiving them
  14. What is split brain operation?
    Cutting of the corpus callosum
  15. What is unilateral neglect?
    Failure to notice things in left field
  16. What does the meninges do?
    Line and protect the CNS
  17. 3 layers of the meninges
    • Dura mater

    • Pia mater
  18. What is the dura mater?
    Tough outer layer
  19. What is the arachnoid layer?
    Middle vascular layer
  20. What is the pia mater?
    Delicate innermost layer
  21. How does CSF flow down the spinal cord?
    Via the central canal
  22. What are the anatomical planes?
    • Sagittal
    • Horizontal
    • Coronal
  23. What is the sagittal plane?
    Cutting the brain to left and right hemispheres
  24. What is the coronal plane?
    Cutting the brain to front and back
  25. What is the horizontal plane?
    Cutting the brain to top and bottom
  26. Which direction is dorsal?
    Top
  27. Which direction is ventral?
    Bottom
  28. 3 divisions of the brain
    • Prosencephalon
    • Mesencephalon
    • Rhombencephalon
