Subjects : gre, psychology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






2. Most brain communications are with the opposite side of the body






3. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






4. Is used as an anaesthetic for children and animals but causes psychosis in adults






5. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






6. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential






7. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






8. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






9. Facial Nerve - moves face and salivates






10. The female reproductive cycle of mammals other than primates






11. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






12. Skin senses that register the sensations of pressure - warmth and cold






13. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






14. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






15. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






16. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






17. Is a peptide neurotransmitter and a natural painkiller and antianxiety






18. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






19. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






20. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






21. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






22. The maintenance of water balance in the body






23. Trochlear Nerve - moves eye






24. Hypothalamic-pituitary-adrenal axis -controls stress response






25. Opening in the iris; dilates and contracts allowing different levels of light in






26. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






27. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






28. The earlier onset of puberty seen in female animals that are housed with males caused by a pheromone in the male'S urine and first observed in mice






29. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






30. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






31. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






32. Portion of a sensory field to which a cell responds






33. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






34. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






35. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






36. Has a calcium-related role and produces the hormone parathyroid






37. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






38. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






39. Controls sexual activity






40. Accessory Nerve - moves the head






41. Hypoglossal Nerve - moves the tongue






42. Sleep tests (i.e. to diagnosis sleep apnea)






43. Expression of traits






44. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






45. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






46. Decreases with age up until age 30 - then begins to increase *(counter intuitive)*






47. Norepinephrine and serotonin






48. The visual image of the world on the retina






49. Made from within - natural






50. Maintains balance/posture and coordinates body movements
