Gre Psychology: Experimental/natural Science Biology

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. Self-dissolving






2. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






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






4. Are found in the diencephalon






5. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






6. Maintains balance/posture and coordinates body movements






7. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






8. Pass the easiest through the blood-brain barrier






9. Dorsal part of midbrain; includes the superior and inferior colliculi






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






11. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






12. Hormones that reduce pain






13. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






14. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






15. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






16. Regulates body temperature






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






18. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






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






20. Controls sexual activity






21. Binding of drug to receptor site that doesn'T interfere with the principal ligand






22. Measure changes in the electrical resistance of the skin (sweat gland activity)






23. Cumulative effects of repeated stimulation from a presynaptic neuron






24. Trochlear Nerve - moves eye






25. Projects to ventral tegmental area






26. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






27. Moving forward






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






29. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






30. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






31. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






32. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






33. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






34. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






35. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






36. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






37. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






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






39. Cells that integrate information across the retina; rather than sending signals toward the brain - amacrine cells link bipolar cells to other bipolar cells and ganglion cells to other ganglion cells






40. 'little net'






41. Sleepwalking - sleep talking






42. Begins where spinal cord ends - 3 structures: the medulla - the pons - the cerebellum






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






44. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






45. Made from within - natural






46. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






47. 'covering'






48. Is characteristic of indirect antagonist drugs






49. 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






50. Vestibulocochlear Nerve - hearing and balance
