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. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






2. Reduces anxiety - released with NE in amygdala - hippocampus - basal ganglia - periaqueductal gray region - locus coeruleus and PFS; NPY is diminished in persons with PTSD/CPTSD and those exposed to chronic stress






3. An ovary or teste






4. Self-dissolving






5. Adenine - Guanine - Thymine - Cytosine






6. Supernormal






7. ...






8. Emotional perception and expression (particularly fearful emotions and detection of threat)






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






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






11. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






12. Glossopharyngeal Nerve - taste swallow






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






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






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






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






17. Is regulated by the hypothalamus






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






19. Is characteristic of indirect antagonists






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






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






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






23. Trochlear Nerve - moves eye






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






25. 'little net'






26. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






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






28. Found in the ventricles and spinal canal






29. 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)






30. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






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






32. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






33. Has a calcium-related role and produces the hormone parathyroid






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






35. Transparent substance between lens and retina






36. Vestibulocochlear Nerve - hearing and balance






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






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






39. Oculomotor Nerve - moves eye pupil






40. Hormones that reduce pain






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






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






43. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






44. Has neurons for reflexes






45. Links the nervous system and endocrine system; comprised of involuntary efferent neurons and divided into the Sympathetic and Parasympathetic branches: Sympathetic Nervous System is involved in the 'fight or flight' response and the Parasympathetic N






46. Increases heartrate - dilates/constricts blood vessels - increases blood sugar - produces hormones epinephrine and norepinephrine






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






48. Is used to treat Parkinson'S Disease






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






50. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)
