  1. Studies related to the neurotransmitters of the brain and our behavior
    BioPsychology
  2. Mind and Body are the same substance
    Monoism
  3. Physical world mind and body are seperate
    Dualism
  4. Hydrolic model; animal spirits flow through nerves responsible for behavior - pereal gland
    Descartes
  5. Electricity makes a frogs leg move; connection between physical explanation for behavior
    Gialvani
  6. Stimulated dog's brain to conduct movement
    Fritz
  7. Speed of Neuron conduction
    Helmholtz
  8. Specific functions in specific brain areas
    Localization
  9. Correlation to function to specific areas of the brain. 35 bumps on the head responsible for a person's emotion and intellect.
    Phrenology
  10. Specific brain areas for speech, thought and movement
    Function Areas
  11. Brain functions as a whole unit and not individually; opposite of phrenology
    Equipotentiality
  12. The smallest unit of heredity that makes protein. They are located on the chromosomes
    Gene
  13. How many chromosomes are there?
    46 chromosomes; 23 from Male & 23 from Female
  14. Double-Helix that contains all genes nudeotides volnerability - genes can contribute to a predisposition
    DNA
  15. Indicates how much of a trait is due to genes
    Heredability
  16. Specialized cells that convey information in chemical and electrical forms, transmit commands in other areas, and generate thought emotion and memory
    Neurons
  17. Recieves information from the outside world or other cells
    Dendrites
  18. Carrys information to other neurons (or muscle organs)
    Axons
  19. Branches at the end of axons
    Terminals
  20. The difference in electric charge between the inside and outside of an inactive neuron's membrane
    Resting Potential
  21. A force that moves ions from the side of the membrane where they are most abundant to the side where they are least abundant
    Force of diffusion
  22. These ions are concentrated on the outside of a neuronal membrane
    Sodium ions
  23. These ions are concentrated on the inside of a neuronal membrane
    Potassium ions
  24. A force which repels ions from the side of the membrane with the same charge and attracts them to the side with the opposite charge
    Electrostatic pressure
  25. A brief depolarization of the neural membrane that enables the neuron to communicate over long distances
    Action Potential
  26. Periods of reduced or zero responsiveness
    Refactory Period
  27. During this period, sodium channels will not reopen, and therefore the axon cannot fire again
    Absolute refactory period
  28. the few miliseconds after the absolute refactory period when the potassium channels remain partially open and the membrane has mostly recovered
    Relative refactory period
  29. Gaps between segments of myelin
    Nodes of Ranvier
  30. The connection between two neurons
    Synapse
  31. Causes excitation or inhibition of the post-synaptic membrane by opening channels directly
    Ionotropic synapses
  32. opens ion channels indirectly and slowly to produce longer lasting effects
    Metabotrophic synapses
  33. Most neurotransmitters are actively transported back into the terminals of the presynaptic cell
    Reuptake
  34. Neurons that adjust the number or sensitivity of their receptors to compensate for fluctuations in neurotransmitter release
    Postsynaptic
  35. Regulates synaptic activity
    Glia
  36. The brain and spinal cord
    The Central Nervous System
  37. Bundle of axons in the CNS
    Tract
  38. Group of cell bodies in the CNS
    Nucleus
  39. Bundles of axons in the peripheral nervous system
    Nerve
  40. Group of cell bodies in the peripheral nervous system
    Ganglion
  41. Involved in planning movements, and works together with the basal ganglia
    Secondary Motor cortex
  42. Involved in speech production
    Broca's area
  43. The largest and one of the most important regions of the human brain. Also plays an important role in organizing and planning.
    Prefrontal cortex
  44. Important for body sensation and spatial location
    Parietal lobe
  45. A surgical procedure that disconnects the prefrontal area from the rest of the brain
    Frontal lobotomy
