Gre Psychology: Experimental/natural Science Biology

Subjects : gre, psychology
  • 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. Audition: protrusions on top of midbrain; part of auditory system

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

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

4. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)

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

6. Vagus Nerve - heart rate and digestion

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

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

9. Include tolerance (possible withdrawal) and sensitivity

10. Optic Nerve - sight

11. Hormones that reduce pain

12. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)

13. Are postsynaptic potentials that are found in the dendrites and vary in their intensity

14. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level

15. Also known as ABLATION - is any surgically induced brain lesion

16. 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

17. The viscous substance between cornea and lens

18. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)

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

20. Hypoglossal Nerve - moves the tongue

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

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

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

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

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

26. Is found in the frontal lobe (which is divided into the prefrontal lobes and ___ ___)

27. Functions as both a hormone and a neurotransmitter in the brain

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. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important

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

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

32. 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

33. Olfactory Nerve - smell

34. Is an oversensitivity to dopamine (D2)

35. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone

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

37. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.

38. Maintains balance/posture and coordinates body movements

39. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei

40. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response

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

42. Produce drowsiness and sleepiness

43. 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

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

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

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

47. Important to motor system

48. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior

49. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior

50. Sign
