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






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






3. Maintains balance/posture and coordinates body movements






4. Mechanism whereby neurons make connections to new areas to change their connectivity






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






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






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






8. Hormones that reduce pain






9. Can occur after long term antipsychotic tx (opposite of Parkinson'S?); oversensitivity to dopamine






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






11. Referred to as the satiety center; lesions lead to obesity and hyperphagia






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






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






14. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






15. The visual image of the world on the retina






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






17. 'covering'






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






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






20. Norepinephrine and serotonin






21. Controls sexual activity






22. Vestibulocochlear Nerve - hearing and balance






23. Moving forward






24. Include tolerance (possible withdrawal) and sensitivity






25. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






26. Is characteristic of indirect antagonists






27. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior






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






29. Transparent substance between lens and retina






30. Made from within - natural






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






32. Consummatory stimulus






33. 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)






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






35. 'little brain'






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






37. Are found in the diencephalon






38. 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






39. 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






40. Is increased in its production by training/experience and therefore - associated with memory






41. Is everything anterior to the central sulcus






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






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






45. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






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






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






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






49. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






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