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






2. 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)






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






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






5. Motor neurons found in the Somatic (voluntary) and Autonomic (involuntary) Nervous Systems






6. 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






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






8. Cells that integrate information across the retina; rather than sending signals toward the brain - amacrine cells link bipolar cells to other bipolar cells and ganglion cells to other ganglion cells






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






10. The female reproductive cycle of most primates - including humans; recognized by growth of the lining of the uterus - ovulation - development of a corpus luteum - and (if pregnancy does not occur) menstration






11. Is characteristic of indirect antagonists






12. Include tolerance (possible withdrawal) and sensitivity






13. 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






14. Has neurons for reflexes






15. Controls sexual activity






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






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






18. Holds the lens in place






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






20. 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






21. Norepinephrine and serotonin






22. Also known as ABLATION - is any surgically induced brain lesion






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






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






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






26. Contains delta activity - stages III and IV






27. 'Roof'






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






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






30. Produce drowsiness and sleepiness






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






34. Are direct antagonists; binds with a receptor but does not activate it - but prevents the natural ligand from binding with the receptor






35. Measure changes in the electrical resistance of the skin (sweat gland activity)






36. Oculomotor Nerve - moves eye pupil






37. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






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






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






40. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






41. Optic Nerve - sight






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






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






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






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






46. Trochlear Nerve - moves eye






47. 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






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






49. Attaches to the binding site on a receptor and interferes with the receptor'S action - but NOT by interfering with the principal ligand'S binding site (noncompetitive binding)






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