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. The viscous substance between cornea and lens






2. States that performance is worst at extremely low or extremely high levels of arousal and optimally at an intermediate level






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






4. 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)






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






6. 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






7. Is an oversensitivity to dopamine (D2)






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






9. Functions as both a hormone and a neurotransmitter in the brain






10. Mechanism whereby neurons make connections to new areas to change their connectivity






11. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






12. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






13. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






14. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






15. 'Roof'






16. 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






17. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






18. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






19. Portion of a sensory field to which a cell responds






20. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






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






22. 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






23. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






24. 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






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






26. Vestibulocochlear Nerve - hearing and balance






27. Is found in the interior rostral temporal lobe - part of limbic system






28. Maintains balance/posture and coordinates body movements






29. Caudate nucleus and putamen






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






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






32. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






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






34. 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






35. 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






36. Self-dissolving






37. Is characteristic of indirect antagonists






38. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






39. Glossopharyngeal Nerve - taste swallow






40. Expression of traits






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






42. Colored part of the eye






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






44. Two different presynaptic neurons/inputs to a post-synaptic cell






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






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






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






48. Optic Nerve - sight






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






50. Found in the ventricles and spinal canal
