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






2. Is used to treat Parkinson'S Disease






3. Moving forward






4. Decreasing effects of a medication due to repeated administration






5. Colored part of the eye






6. If a synapse is active at about the same time that a postsynaptic neuron is active - that synapse will be strengthened






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






8. Contains delta activity - stages III and IV






9. Found in the ventricles and spinal canal






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






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






12. 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






13. Serotonin = 5-HT -regulation of mood - anxiety - aggression - sleep - appetite - sexuality -rostral and caudal raphe nuclei






14. Is regulated by the hypothalamus






15. 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)






16. Transparent substance between lens and retina






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






18. Is a loss of dopamine cells in the substantia nigra of the basal ganglia; these cells are usually dark (nigra) but in Parkinson'S - the substantia nigra appears white due to cell death

19. Regulates body temperature






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






21. 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






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






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






24. An ovary or teste






25. Vision: protrusions on top of the midbrain; part of visual system






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






27. Is found between the dura mater and arachnoid mater meninges






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






29. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






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






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






32. 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






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






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






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






36. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






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






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






39. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

40. Vestibulocochlear Nerve - hearing and balance






41. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






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






43. Precursor to the catecholamine neurotransmitters (DA + NE)






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






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






46. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






47. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






48. Has a calcium-related role and produces the hormone parathyroid






49. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






50. Is used as an anaesthetic for children and animals but causes psychosis in adults
