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. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






2. Sleepwalking - sleep talking






3. Vagus Nerve - heart rate and digestion






4. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






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






6. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






7. 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






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






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






10. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






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






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






13. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






14. Projects to ventral tegmental area






15. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






16. Expression of traits






17. 'little brain'






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






19. Found in the hypothalamus - function to maintain the water balance in the body






20. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






21. 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)






22. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






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






24. Some brain communications are with the same side of the body






25. Hypoglossal Nerve - moves the tongue






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






27. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






28. Include tolerance (possible withdrawal) and sensitivity






29. An ovary or teste






30. 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)






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






32. ...






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






34. Adenine - Guanine - Thymine - Cytosine






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






36. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






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






38. Transparent substance between lens and retina






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






40. Is regulated by the hypothalamus






41. Affect multiple receptors; highly preferential to which type of receptor they affect






42. Olfactory Nerve - smell






43. Glossopharyngeal Nerve - taste swallow






44. Trochlear Nerve - moves eye






45. 'covering'






46. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






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






48. 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






49. Regulates body temperature






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