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. Is found between the dura mater and arachnoid mater meninges






2. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






3. Maintains balance/posture and coordinates body movements






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






5. 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)






6. Affect multiple receptors; highly preferential to which type of receptor they affect






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






8. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






9. Choroid Plexus > Ventricle 1 & 2 > Foramen of Monro > Ventricle 3 > Aqueduct of Sylvius > Ventricle 4 > Foramen of Magendie lateral aperture) > Foramina of Luschka (lateral aperture) - subarachnoid space (outside of brain) and spinal cord > re-absorp






10. Binding of drug to receptor site that doesn'T interfere with the principal ligand






11. Optic Nerve - sight






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






13. Supernormal






14. Found in the hypothalamus - function to maintain the water balance in the body






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






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






17. Trigerminal Nerve - face sensation






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






19. Occurs when an external stimulation - regardless of intensity - will not trigger a new action potential






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






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






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






23. A BEHAVIOR; insistent urge of sleepiness forces us to seek sleep/a bad






24. Begins where spinal cord ends - 3 structures: the medulla - the pons - the cerebellum






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






26. Has neurons for reflexes






27. Skin senses that register the sensations of pressure - warmth and cold






28. 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)






29. Are found in the diencephalon






30. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






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






32. 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)






33. Vision: protrusions on top of the midbrain; part of visual system






34. 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






35. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






36. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






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






38. First described by Descartes - a combination of antagonistic muscle movements (e.g. those involved in walking)






39. 'little brain'






40. Synchronized EEG activity during its deeper stages






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






42. A peptide - also known as OREXIN - produced by neurons whose cell bodies are located in the hypothalamus; their destruction causes narcolepsy






43. 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






44. Decreasing effects of a medication due to repeated administration






45. Is an oversensitivity to dopamine (D2)






46. The visual image of the world on the retina






47. Vagus Nerve - heart rate and digestion






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






49. Regulates body temperature






50. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles
