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






2. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






3. Sudden - sharp waveforms found only in Stage II of sleep; spontaneously occur about one per minute but also to unexpected noises






4. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






5. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






6. Moving forward






7. A chemical released by one animal that affects the behavior or physiology of another animal; usually smelled or tasted






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






9. Sleepwalking - sleep talking






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






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






12. Has neurons for reflexes






13. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






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






15. Absolute; relative






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






17. The slowing and eventual cessation of estrous cycles in groups of female animals that are housed together; caused by a pheromone in the animals urine and first observed in mice






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






19. 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)






20. Midbrain - medulla and the pons






21. Decreasing effects of a medication due to repeated administration






22. learning and memory -neurotransmitter released at the neuromuscular junction of skeletal muscle axons to excite the muscle to contract






23. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






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






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






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






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






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






29. Contains delta activity - stages III and IV






30. Is regulated by the hypothalamus






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






32. An ovary or teste






33. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






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






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






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






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






38. Vagus Nerve - heart rate and digestion






39. The viscous substance between cornea and lens






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






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






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






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






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






45. Important to motor system






46. 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






47. 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






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






49. 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)






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