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






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






3. Supernormal






4. Sign






5. Trigerminal Nerve - face sensation






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






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






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






9. ...






10. Moving forward






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






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






13. Is used to treat Parkinson'S Disease






14. 1. ventral tegmentum to mesolimbic forebrain (cognition - reward systems - emotional behavior) 2. substantia nigra to caudate nucleus putamen (movement and sensory stimulation) 3. hypothalamus to pituitary gland (neuronal/hormonal control)






15. Maintains balance/posture and coordinates body movements






16. SCN = controls circadian rhythms - located directly above the optic chasm in the anterior portion of the hypothalamus - receives input from the eyes which is why light exposure affects our sleep-wake cycles






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






18. Colored part of the eye






19. Irregular electrical activity of 13-30 Hz - state of arousal - attentive






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






21. Smooth electrical activity of 8-12 Hz -medium frequency - awake but in a restful state (^ eyes closed but conscious)






22. The visual image of the world on the retina






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






24. Is used as an anaesthetic for children and animals but causes psychosis in adults






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






26. Neurotransmitter in CNS - hormone in peripheral vascular system; deficiencies > depression - ADD; noradrenergic nuclei = locus coeruleus






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






28. 'Roof'






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






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






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






32. 1. Stage I (non-REM sleep) 2. Stage II (non-REM sleep 3. Stage III (non-REM sleep - slow-wave sleep) 4. Stage IV (non-REM sleep - slow-wave sleep) 5. Rapid Eye Movement Sleep (REM sleep) ~takes about 90 minutes for one full sleep cycle






33. Eating - sex - aggression - sleep - focus on subcortical and neuroendocrine control of behavior






34. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






35. Is characteristic of indirect antagonists






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






37. 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






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






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






40. Controls sexual activity






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






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






43. 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






44. 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






45. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






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






47. Is regulated by the hypothalamus






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






49. Vestibulocochlear Nerve - hearing and balance






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