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. 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






2. Sign






3. Maintains balance/posture and coordinates body movements






4. Absolute; relative






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






6. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






7. Damage to this are causes clumsiness and loss of balance






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






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






10. The maintenance of water balance in the body






11. Vagus Nerve - heart rate and digestion






12. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






13. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






14. 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)






15. 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






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






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






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






19. Are found in the diencephalon






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






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






22. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






23. An ovary or teste






24. Is the primary inhibitory neurotransmitter in vertebrates; these receptors are ionotropic






25. Abducens Nerve - moves eye






26. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






27. Includes the tectum and tegmentum






28. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






29. Measure changes in the electrical resistance of the skin (sweat gland activity)






30. 'covering'






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






32. The viscous substance between cornea and lens






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






34. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






35. Controls sexual activity






36. 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






37. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






38. Is characteristic of indirect antagonist drugs






39. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






40. Sleepwalking - sleep talking






41. 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)






42. Has neurons for reflexes






43. 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






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






45. Is characteristic of indirect antagonists






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






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






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






49. Adenine - Guanine - Thymine - Cytosine






50. Midbrain - medulla and the pons
