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. Colored part of the eye






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






3. 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






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






5. 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






6. Hormones that reduce pain






7. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






8. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






9. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






10. Is regulated by the hypothalamus






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






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






13. Trochlear Nerve - moves eye






14. ...






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






16. Accessory Nerve - moves the head






17. Is everything anterior to the central sulcus






18. 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






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






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






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






22. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






23. The visual image of the world on the retina






24. Are found in the diencephalon






25. The viscous substance between cornea and lens






26. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






27. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






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






29. 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






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






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






32. Supernormal






33. Sign






34. An ovary or teste






35. Is used to treat Parkinson'S Disease






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






37. Important to motor system






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






39. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






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






41. 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






42. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






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






44. Consummatory stimulus






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






46. Adenine - Guanine - Thymine - Cytosine






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






48. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






49. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






50. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2
