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. Symptom of narcolepsy - irresistible urge to

2. Controls sexual activity

3. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)

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

5. 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

6. 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

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

8. Pass the easiest through the blood-brain barrier

9. Increasing effects/effectiveness of a medication due to repeated administration

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

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

12. Moving forward

13. Maintains balance/posture and coordinates body movements

14. 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

15. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)

16. Sign

17. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle

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

19. Sleepwalking - sleep talking

20. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)

21. Transparent substance between lens and retina

22. Self-dissolving

23. 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

24. Supernormal

25. 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)

26. Synchronized EEG activity during its deeper stages

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

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

29. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N

30. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)

31. The viscous substance between cornea and lens

32. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice

33. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery

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

35. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies

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

37. Is characteristic of indirect antagonists

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

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

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

41. All have similar molecular structure - so many 'dirty' medications

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

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

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

46. Accessory Nerve - moves the head

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

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

49. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones

50. Receive incoming sensory information or send out motor impulse commands
