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. Abducens Nerve - moves eye






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






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






4. Accessory Nerve - moves the head






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






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






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






8. Includes the thalamus and hypothalamus; region of forebrain surrounding the 3rd ventricle






9. Colored part of the eye






10. Is a peptide neurotransmitter and a natural painkiller and antianxiety






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






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






13. Norepinephrine and serotonin






14. Midbrain - medulla and the pons






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






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






17. 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)






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






19. Vestibulocochlear Nerve - hearing and balance






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






21. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






22. Self-dissolving






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






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






25. In the CNS - is an amino acid that stabilizes neural activity






26. Is used to treat Parkinson'S Disease






27. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in prefrontal cortex






28. 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






29. Consummatory stimulus






30. Optic Nerve - sight






31. 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






32. Made from within - natural






33. Supernormal






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






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






36. 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)


37. Has neurons for reflexes






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






39. If head is rotated - eye movements occur in the same direction






40. Expression of traits






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






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






43. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






44. Moving forward






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






46. 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






47. Absolute; relative






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






49. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






50. Is found in the interior rostral temporal lobe - part of limbic system
