Brain & Behavior part 1

The flashcards below were created by user Luimi on FreezingBlue Flashcards.

  1. Regionalization
    Idea that the brain is separated into different regions, similarly to how the world is separated into different regions. Each region has a specific function associated with it.
  2. 3 main parts of brain
    Brain stem, limbic system, and cerebral cortex.
  3. Brain stem
    Base of brain. Basic survival functions (maintaining blood pressure, regulating breathing, heart rate.) consists of cerebellum, medulla, pons, and reticular formation.
  4. Limbic system
    Middle "inner guts" of brain. Regulates basic mammalian functions (sexual reproduction, sexual attraction, regulating hunger). Consists of thalamus, hypothalamus, hippocampus, amygdala.
  5. Cerebral Cortex
    "Outer shell" of brain. Advanced cognitive processing (mental processes, things we think about, conscious awareness). Contains occipital lobe, temporal lobe, parietal lobe, frontal lobe.
  6. Continents or Countries?
    3 basic parts of brain are continents. Sub-regions of each part are countries.
  7. Cerebellum
    Part of Brain stem. Coordinated movement, motor control (muscle coordination).
  8. Medulla
    Part of Brain stem. Controls blood pressure, respiration, shuts down when drug overdose occurs.
  9. Pons
    Part of Brain stem. Regulates conscious states (alertness, awake or not).
  10. Reticular Formation
    Part of Brain stem. Sense of touch.
  11. Thalamus
    Limbic System. All senses.
  12. Hippocampus
    Limbic System. Memory Processing. (looks like a seahorse); A medial temporal lobe structure that is important for learning and memory.
  13. Hypothalamus
    Limbic system. Regulates sleep, hunger and thirst, sexual behaviors.
  14. Amygdala
    Limbic System. Processes emotions. "fear center."
  15. Occipital lobe
    Cerebral cortex. Vision (awareness).
  16. Temporal Lobe
    Cerebral cortex. Hearing (awareness)/ language processing (reading and writing.)
  17. Parietal Lobe
    Cerebral cortex. touch (awareness)
  18. Frontal lobe
    Cerebral cortex. motor coordination, "brain power", thoughts and decision making.
  19. Nervous System
    Set of circuits that communicate with each other to control all processes of the body and mind. Central and Peripheral.
  20. Central Nervous System
    Brain, Spinal cord, and Cauda Equina.
  21. Spinal Cord
    Connection between brain and peripheral nervous system.
  22. Peripheral Nervous System
    Contains somatic and autonomic.
  23. Somatic
    "soma" means "body." Contains Motor system and perceptual system. Is under voluntary control and in our conscious awareness.
  24. Autonomic
    "automatic". Contains sympathetic and parasympathetic. Connected to blood pressure, respiration, heart rate, digestions, involuntary control, and subconscious.
  25. Sympathetic
    "Fight or flight". Stress response (cortisol, adrenaline); Activates everything except digestion.
  26. Parasympathetic
    "rest and digest". Deactivates everything except digestion.
  27. White matter
    On an MRI scan, axons (parts of a neuron)
  28. Grey Matter
    On an MRI scan, cell bodies and dendrites (parts of a neuron.)
  29. Corpus Callosum
    Connection between right brain and left brain. "telephone wires" Physical bridge and communicator.
  30. Ventricles
    "empty" spaces allow secondary circulation, spinal fluid, and cushions brain.
  31. Neuroscience
    Study of the nervous system.
