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. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






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






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






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






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






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






7. Norepinephrine and serotonin






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






9. Stimulates bone growth and produces the hormones: somatotropin - prolactin - thyroid-stimulating - adrenocorticotropic (ACTH) - follicle-stimulating - luteinnizing






10. The female reproductive cycle of mammals other than primates






11. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






12. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






13. Trochlear Nerve - moves eye






14. There are 12 add more






15. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






16. The viscous substance between cornea and lens






17. Tremors - rigidity of limbs - poor balance and difficulty initiating movements


18. Two different presynaptic neurons/inputs to a post-synaptic cell






19. The maintenance of water balance in the body






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






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






22. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






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






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






25. Abducens Nerve - moves eye






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






27. Is a loss of dopamine cells in the substantia nigra of the basal ganglia; these cells are usually dark (nigra) but in Parkinson'S - the substantia nigra appears white due to cell death


28. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






29. Colored part of the eye






30. The increase in REM sleep seen after a period of REM sleep deprivation






31. Vestibulocochlear Nerve - hearing and balance






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






33. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






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






35. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






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






37. Projects to ventral tegmental area






38. Damage to this are causes clumsiness and loss of balance






39. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






40. Decreasing effects of a medication due to repeated administration






41. 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






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






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






44. Produce drowsiness and sleepiness






45. Is increased in its production by training/experience and therefore - associated with memory






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






47. 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






48. 'covering'






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






50. Referred to as the satiety center; lesions lead to obesity and hyperphagia
