Across
  1. 3. the division of the autonomic nervous system that calms the body, conserving its energy
  2. 4. A person with this type of aphasia cannot speak in clear words, BUT can understand you.
  3. 7. Potential: The electrical charge that travels down the axon of a neuron.
  4. 10. controls language reception; brain area involved in language comprehension and expression
  5. 11. the space between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron
  6. 12. This "brain" regulates emotions and includes the hippocampus, amygdala and hypothalamus
  7. 13. This "brain" is oldest part and central core. It is responsible for automatic survival functions. AKA “The reptile brain.”
  8. 16. maintaining a balanced internal equilibrium, such as temperature, blood glucose and hydration around a particular level.
  9. 21. tissue destruction to examine brain tissue
  10. 22. periodic, natural loss of consciousness distinct from unconsciousness from a coma, general anesthesia, or hibernation
  11. 23. __________Scan A diagnostic method of examining the inside of the body, using hundreds of x-ray images from different angles that are combined by a computer to build up a 3d detailed picture
  12. 27. _______vu that eerie sense that “I’ve experienced this before;” cues from the current situation may unconsciously trigger retrieval of an earlier experience
  13. 28. These rhythms are physical, mental, and behavioral changes that follow a 24-hour cycle and encourage sleep. These natural processes respond primarily to light and dark and affect most living things, including animals, plants, and microbes.
  14. 29. _________scan a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task
  15. 30. a part of the brain that is ths control center of the endocrine system. It regulates the pituitary gland & Homeostasis.
  16. 34. This division of the Peripheral nervous system controls voluntary muscle movements.
  17. 36. recurring problems in falling or staying asleep
  18. 40. psychedelic drugs , like LSD, that distort perceptions and evoke sensory images in the absence of sensory input
  19. 41. A sleep Disorder where a person stops breathing during sleep
  20. 43. Night________ a sleep disorder characterized by high arousal and an appearance of being terrified.
  21. 44. A small structure on the brainstem that relays motor and sensory signals to the cerebral cortex. Damage to this area leads to coma
  22. 45. the brain’s ability to reorganize itself by forming new neural connections throughout life
  23. 46. these neurons carry outgoing information from the brain and spinal cord to the muscles and glands; efferent neurons
  24. 47. drugs (such as alcohol, barbiturates, and opiates) that reduce neural activity and slow body functions
  25. 48. two almond–sized neural clusters in the limbic system that prepare us for life and death situations. They are at the root of anxiety attacks
  26. 49. the mental state of being awake and aware of one's surroundings. Alterations in this state include sleep, hypnosis or Coma
  27. 50. ________Sheath a fatty tissue layer segmentally encasing the axons of some neurons; enables vastly greater transmission speed as neural impulses hop from one node to the next
  28. 51. drugs (such as caffeine, nicotine, and the more powerful amphetamines, cocaine, Ecstasy, and methamphetamine) that excite neural activity and speed up body functions
  29. 52. a nerve cell; the basic building block of the nervous system
Down
  1. 1. _____ Cortex: an area at the rear of the frontal lobes that controls voluntary movements
  2. 2. Sleep disorder characterized by overwhelming daytime drowsiness with sudden attacks of sleep
  3. 5. _________Cortex: This "brain" is the wrinkled layer of gray matter that covers the outside of the brain and is associated with higher cognitive functions, such as language, learning, perception, and planning.
  4. 6. A sleep disorder where what happens in your dream gets acted out in real life while still asleep
  5. 8. _________Syndome is a chromosomal disorder in females in which either an X chromosome is missing, or part of one X chromosome is deleted.
  6. 9. The end of a chromosome that holds DNA together like Aglates on a shoelace
  7. 14. a neurotransmitter believed to help regulate mood and social behavior, appetite and digestion, sleep, memory, and sexual desire and function
  8. 15. a Suggestion made during a hypnosis session, it’s to be carried out after the subject is no longer hypnotized; used by some clinicians to help control undesired symptoms and behaviors
  9. 17. a molecule that, by binding to a receptor site blocks a response
  10. 18. cells in the nervous system that support, nourish, and protect neurons. They are the most numerous cells in the brain
  11. 19. ______Neurons carry incoming information from the sensory receptors to the brain and spinal cord
  12. 20. This hypothesis suggests dreams are created by changes in neuron activity that activates the brainstem during REM sleep
  13. 24. a recurring sleep stage during which vivid dreams commonly occur; also known as paradoxical sleep because the muscles are relaxed (except for minor twitches) but other body systems are active
  14. 25. The lobe of the Cerebral cortex responsible for processing visual information
  15. 26. __________processing theory dream theory based on idea that humans process the information they receive, rather than merely responding to stimuli
  16. 31. division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations
  17. 32. a molecule that, by binding to a receptor site, stimulates a response
  18. 33. the diminishing effect with regular use of the same dose of a drug, requiring the user to take larger and larger doses before experiencing the drug’s effect
  19. 35. A chemical substance, such as acetylcholine or dopamine, transmits nerve impulses across a synapse.
