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. Optic Nerve - sight






2. The visual image of the world on the retina






3. 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






4. Include tolerance (possible withdrawal) and sensitivity






5. Olfactory Nerve - smell






6. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






7. An area that combines input from diverse brain regions






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






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






10. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






11. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






12. Hypoglossal Nerve - moves the tongue






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






14. 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






15. 'little brain'






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






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






18. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






19. Controls sexual activity






20. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






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






22. Convoluted of hills (gyri) and valleys (sulci) divided into two hemispheres (left and right) which are further divided into four lobes (occipital - parietal - temporal and frontal)






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






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






25. 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






26. Audition: protrusions on top of midbrain; part of auditory system






27. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






28. Portion of a sensory field to which a cell responds






29. Contains delta activity - stages III and IV






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






31. Extensive research in dreams - said BAH to Freud; proposed the activation-synthesis hypothesis (dreams are nothing more than the product of random electrical impulses)






32. 'covering'






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






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






35. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






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






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






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






39. Ventral part of midbrain - includes periaqueductal gray matter - reticular formation - red nucleus - and substantia nigra






40. Is regulated by the hypothalamus






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






42. 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






43. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






44. Trigerminal Nerve - face sensation






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






46. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






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






48. Supernormal






49. Made from within - natural






50. Synchronized EEG activity during its deeper stages
