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. Transparent substance between lens and retina






2. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






3. Optic Nerve - sight






4. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






5. Viscous substance between cornea and lens; transparent substance between lens and retina






6. 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






7. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






8. A single - unfertilized cell created during conception; the combined egg + sperm






9. Vagus Nerve - heart rate and digestion






10. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






11. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






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






13. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






14. Audition: protrusions on top of midbrain; part of auditory system






15. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






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






17. 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






18. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






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






20. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






21. Hormones that reduce pain






22. Self-dissolving






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






24. Hypoglossal Nerve - moves the tongue






25. If a synapse is active at about the same time that a postsynaptic neuron is active - that synapse will be strengthened






26. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit


27. Vision: protrusions on top of the midbrain; part of visual system






28. 'Roof'






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






30. Supernormal






31. Consummatory stimulus






32. Decreasing effects of a medication due to repeated administration






33. ...






34. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






35. Found in the ventricles and spinal canal






36. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






37. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






38. Vestibulocochlear Nerve - hearing and balance






39. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






40. Contains delta activity - stages III and IV






41. 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






42. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)






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






44. Includes the tectum and tegmentum






45. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






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






47. Is an oversensitivity to dopamine (D2)






48. Holds the lens in place






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






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