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






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






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






4. Trochlear Nerve - moves eye






5. Pass the easiest through the blood-brain barrier






6. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






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






8. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






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






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






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






12. Is an oversensitivity to dopamine (D2)






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






14. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






15. Vagus Nerve - heart rate and digestion






16. 'covering'






17. 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)






18. 'little net'






19. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






20. Somewhat excitatory - also involved in synaptic plasticity - learning and short-term memory






21. Has a major role in metabolism - stimulation/maintenance - produces the hormones thyroxin and calcitonin






22. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






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






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






25. Attaches to a binding site on receptor and interferes with the action of the receptor without affecting the binding site for the principal ligand (noncompetitive binding)






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






27. Hypoglossal Nerve - moves the tongue






28. Located underneath the cerebral cortex and includes the bottom portion of the forebrain - cerebellum - basal ganglia - medulla - pons - midbrain - thalamus - hypothalamus - amygdala - hippocampus






29. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






30. 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






31. Expression of traits






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






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






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






35. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






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






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






38. 'Roof'






39. 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)






40. Sign






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






42. Consummatory stimulus






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






44. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






45. ...






46. Facial Nerve - moves face and salivates






47. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






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






49. Maintains balance/posture and coordinates body movements






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