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. Vestibulocochlear Nerve - hearing and balance






2. Optic Nerve - sight






3. The female reproductive cycle of mammals other than primates






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






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






6. Moving forward






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






8. Regulates body temperature






9. Contains delta activity - stages III and IV






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






11. Controls sexual activity






12. Supernormal






13. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






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






15. Stimulates bone growth and produces the hormones: somatotropin - prolactin - thyroid-stimulating - adrenocorticotropic (ACTH) - follicle-stimulating - luteinnizing






16. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






17. Abducens Nerve - moves eye






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






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






20. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






21. Consummatory stimulus






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






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






24. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






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






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






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






28. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






29. Occurs for body temperature - blood glucose levels - blood concentration - etc -hormones are important






30. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)






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






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






33. 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






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






35. 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)






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






37. Is everything anterior to the central sulcus






38. Transparent substance between lens and retina






39. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






40. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






41. 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)






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






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






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






45. Damage to this are causes clumsiness and loss of balance






46. The scientific study of animal behavior; documentation of species-specific instinctual behaviors






47. Instead of one continuum for sex (masculine-feminine) - her work in the presence of both masculine and feminine features/development suggests these are actually two separate continuums (defeminized-feminized and unmasculinized-masculinized)

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






49. Self-dissolving






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