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. Trochlear Nerve - moves eye






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






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






4. Consummatory stimulus






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






6. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






7. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






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






9. Self-dissolving






10. Optic Nerve - sight






11. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






12. Most pervasive excitatory neurotransmitter in the brain






13. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






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. Has two lobes that are connected by the massa intermedia (looks like a pair of balls - without the nutsack)






16. Is found between the arachnoid mater and Pia mater; this is where CSF cushions (and bathes) the brain - giving it the floating quality (and keeping it moist/circulating)






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






18. Part of limbic system; protrusion of the bottom of the brain at the posterior end of the hypothalamus - contains some hypothalamic nuclei






19. EEG desynchrony (rapid -irregular waves) - lack of muscle tonus - rapid eye movements - penile erection/vaginal secretion - dreams; EEG synchrony (slow waves) - moderate muscle tonus - slow/absent eye movements - lack of genital activity






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






21. Found in the ventricles and spinal canal






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






23. Located in the midbrain - a group of neurons which produce dopamine and degenerate in Parkinson'S Disease






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






25. Controls sexual activity






26. Caudate nucleus and putamen






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






28. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






29. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






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






31. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






32. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






33. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






34. Are found in the diencephalon






35. 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






36. These two brain structures contain entry/exits for most of the cranial nerves and control vital functions (heart rate -digestion - respiration)






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






38. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






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






40. Some brain communications are with the same side of the body






41. Synchronized EEG activity during its deeper stages






42. ...






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






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






45. 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)






46. Holds the lens in place






47. One of the primary noradrenergic nuclei whose ascending axons project to frontal cortex - thalamus - hypothalamus - limbic system






48. Include tolerance (possible withdrawal) and sensitivity






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






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