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. 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






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






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






4. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






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






6. Hypoglossal Nerve - moves the tongue






7. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






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






9. Controls sexual activity






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






11. Is characteristic of indirect antagonists






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






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






14. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)






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






16. Synchronized EEG activity during its deeper stages






17. Holds the lens in place






18. Cumulative effects of repeated stimulation from a presynaptic neuron






19. Olfactory Nerve - smell






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. Midbrain - medulla and the pons






22. 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






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






24. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






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






26. The increase in REM sleep seen after a period of REM sleep deprivation






27. 'little net'






28. Accessory Nerve - moves the head






29. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






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






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






32. Dorsal part of midbrain; includes the superior and inferior colliculi






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






34. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






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






36. A single - unfertilized cell created during conception; the combined egg + sperm






37. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






38. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






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






40. Adenine - Guanine - Thymine - Cytosine






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






42. Is an oversensitivity to dopamine (D2)






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






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






45. 'little brain'






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






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






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






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






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