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. Midbrain - medulla and the pons






2. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






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






4. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






5. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






6. 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






7. Hormones that reduce pain






8. 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






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






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






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






12. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






13. Pass the easiest through the blood-brain barrier






14. Include tolerance (possible withdrawal) and sensitivity






15. Cumulative effects of repeated stimulation from a presynaptic neuron






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






17. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






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






19. Moving forward






20. 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)






21. Strip of limbic cortex lying along the lateral walls of the groove separating the cerebral hemispheres - just above the corpus callosum






22. 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






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






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






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






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






27. Transparent substance between lens and retina






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






29. Projects to ventral tegmental area






30. Controls sexual activity






31. 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






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






33. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






34. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






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






36. Audition: protrusions on top of midbrain; part of auditory system






37. 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






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






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






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






41. Abducens Nerve - moves eye






42. Combines input from diverse brain regions; receives sensory information/sends motor impulses






43. 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)






44. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






45. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






46. 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

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






49. Is characteristic of indirect antagonists






50. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods
