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. Produce drowsiness and sleepiness






2. Optic Nerve - sight






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






4. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






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






6. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






7. Is used to treat Parkinson'S Disease






8. 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)

9. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






10. Pass the easiest through the blood-brain barrier






11. There are 12 add more






12. Found in the ventricles and spinal canal






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






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






15. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






16. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






17. Symptom of narcolepsy - irresistible urge to






18. 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






19. Midbrain - medulla and the pons






20. Include tolerance (possible withdrawal) and sensitivity






21. Caudate nucleus and putamen






22. Cumulative effects of repeated stimulation from a presynaptic neuron






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






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






25. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






26. 'little brain'






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






28. 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






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






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






31. 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

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






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






34. Facial Nerve - moves face and salivates






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






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






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






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






39. 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)






40. 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)






41. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






42. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






43. Focuses light waves on the retina and is held in place by the suspensory ligament; aqueous humor on cornea side; vitreous humor on retina side






44. Emotional perception and expression (particularly fearful emotions and detection of threat)






45. Expression of traits






46. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






47. Controls sexual activity






48. An ovary or teste






49. The visual image of the world on the retina






50. Sleep tests (i.e. to diagnosis sleep apnea)
