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






2. Transparent substance between lens and retina






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






4. Is found at the base of the brain - underneath the thalamus (**remember hypo-below)






5. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






6. Symptom of narcolepsy - paralysis occurring just before a person falls alseep






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






8. Two different presynaptic neurons/inputs to a post-synaptic cell






9. Vagus Nerve - heart rate and digestion






10. Has neurons for reflexes






11. When a neuron reaches its excitation threshold - the neuron will produce an action potential of FIXED amplitude regardless of the magnitude of the stimulation






12. Is everything anterior to the central sulcus






13. Readiness with which molecules/drugs/medications join together; varies widely from medication to medication






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






15. 3 layers of tissues that cover and protect CNS; dura mater (outermost layer) - arachnoid mater (middle layer) - Pia mater (innermost layer)






16. Decreasing effects of a medication due to repeated administration






17. Olfactory Nerve - smell






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






19. Sits just above the hindbrain - contains cranial nerves - parts of the reticular formation -important relay stations for sensory information and the substantia nigra






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






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






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






23. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






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






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






26. A peptide - also known as OREXIN - produced by neurons whose cell bodies are located in the hypothalamus; their destruction causes narcolepsy






27. Pass the easiest through the blood-brain barrier






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






29. Regulates body temperature






30. Important to motor system






31. Colored part of the eye






32. These cells perform a variety of functions but do not transmit information; one type forms the myelin sheath






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






34. Trigerminal Nerve - face sensation






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






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






37. Most pervasive excitatory neurotransmitter in the brain






38. 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)






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






40. Trochlear Nerve - moves eye






41. An axon of a neuron in one region of the brain whose terminals form synapses with neurons in another region






42. 'little net'






43. Produce drowsiness and sleepiness






44. Referred to as the satiety center; lesions lead to obesity and hyperphagia






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






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






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






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






49. Abducens Nerve - moves eye






50. Is used to treat Parkinson'S Disease
