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. Pass the easiest through the blood-brain barrier






2. Cumulative effects of repeated stimulation from a presynaptic neuron






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






4. Include tolerance (possible withdrawal) and sensitivity






5. Self-dissolving






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






7. Vestibulocochlear Nerve - hearing and balance






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






9. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






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






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






12. Is found between the dura mater and arachnoid mater meninges






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






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






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






16. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






17. Trochlear Nerve - moves eye






18. 'little brain'






19. Trigerminal Nerve - face sensation






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






21. 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






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






23. 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






24. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






25. Synchronized EEG activity during its deeper stages






26. Opening in the iris; dilates and contracts allowing different levels of light in






27. In the CNS - is an amino acid that stabilizes neural activity






28. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






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






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






31. Are postsynaptic potentials that are found in the dendrites and vary in their intensity






32. Vagus Nerve - heart rate and digestion






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






34. Has a calcium-related role and produces the hormone parathyroid






35. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






36. Controls sexual activity






37. Moving forward






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






39. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

40. 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)






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






42. Abducens Nerve - moves eye






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






44. Holds the lens in place






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






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






47. ...






48. Produce drowsiness and sleepiness






49. Most pervasive excitatory neurotransmitter in the brain






50. Regulates body temperature
