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






2. 'covering'






3. Moving forward






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






5. Is found between the dura mater and arachnoid mater meninges






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






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






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






9. 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






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






11. Sleepwalking - sleep talking






12. Is found in the interior rostral temporal lobe - part of limbic system






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






14. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






15. Supernormal






16. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






17. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






18. Abducens Nerve - moves eye






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






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






21. Result in either tolerance (and possible withdrawal symptoms) or sensitization (increase effectiveness of the drug)






22. 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

23. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






24. 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






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






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






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






28. Made from within - natural






29. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






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






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






32. ...






33. Regulates body temperature






34. Adenine - Guanine - Thymine - Cytosine






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

36. 'little brain'






37. In the CNS - is an amino acid that stabilizes neural activity






38. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior






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






40. Is used to treat Parkinson'S Disease






41. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






42. Is characteristic of indirect antagonists






43. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






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






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






46. The visual image of the world on the retina






47. Emotional perception and expression (particularly fearful emotions and detection of threat)






48. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






49. Sign






50. Pleasure center of the brain; discovered by Olds & Milner
