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 regulated by the hypothalamus






2. Sleep tests (i.e. to diagnosis sleep apnea)






3. 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






4. Projects to ventral tegmental area






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






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






7. Oculomotor Nerve - moves eye pupil






8. 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






9. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






10. These two developed the criteria for habituation; basic process is a form of synaptic depression that occurs presyntaptically.






11. If a synapse is active at about the same time that a postsynaptic neuron is active - that synapse will be strengthened






12. 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






13. Is generated by photoreceptors that are only sensitive to degrees of brightness; black-and-white vision found in the rods






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






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






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






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






18. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






19. Cumulative effects of repeated stimulation from a presynaptic neuron






20. 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)






21. Vestibulocochlear Nerve - hearing and balance






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






23. Precursor to GABA (the most inhibitory/regulatory/pervasive neurotransmitter)






24. Regulates body temperature






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






26. 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






27. All have similar molecular structure - so many 'dirty' medications






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






29. An inherited form of defective color vision in which hues with short wavelengths are confused (blue cone dysfunction); see world in green and red






30. Those biological considerations which are IMMEDIATE;Behavioral/Cognitive Neuroscience (i.e. how the nervous and endocrine systems influence behaviors/thoughts)






31. 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)






32. Hormones that reduce pain






33. Is used to treat Parkinson'S Disease






34. Precursor to the catecholamine neurotransmitters (DA + NE)






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






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






37. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






38. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






39. 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)






40. Occurs under drug-induced conditions - including excessive use of marijuana; high body temperature - autonomic instability and muscle rigidity






41. Include indolamines (serotonin) and catecholamines (dopamine - norepinephrine and epinephrine)






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






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






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






45. Adenine - Guanine - Thymine - Cytosine






46. Pleasure center of the brain; discovered by Olds & Milner






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






48. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






49. Is a receptor blocker; binds with a receptor but does not activate it - actually prevents the natural ligand from binding with the receptor






50. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum
