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. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






2. hormone - secreted by the pituitary gland -signals the adrenal gland to secrete corticosteroid hormones -ACTH is a critical component of the HPA Axis that controls the stress response






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






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






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






6. 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






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






8. 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)






9. 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






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






11. There are 12 add more






12. Is characteristic of indirect antagonists






13. An anterograde amnesia in which one cannot form episodic memories BUT in experiments - patients that cannot identify previously heard melodies do show a preference for them -> explicit memory function has a different neurological basis than implicit

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






15. Include the Nigrostriatal system - Mesolimbic system and Mesocortical system






16. Self-dissolving






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






18. Areas in the brain receiving incoming sensory information or sending out motor-impulse commands






19. Expression of traits






20. Dorsal part of midbrain; includes the superior and inferior colliculi






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






22. A steroid hormone produced by the ovary that maintains the endometrial lining of the uterus during the later part of the menstrual cycle and during pregnancy; along with estradiol it promotes receptivity in female mammals with estrous cycles






23. Adenine - Guanine - Thymine - Cytosine






24. The scientific study of animal behavior; documentation of species-specific instinctual behaviors






25. 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)






26. Part of a glial cell that wraps around the axon of a neuron - providing insulation that facilitates speed of propagation of action potential






27. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






28. Are found in the diencephalon






29. Receive incoming sensory information or send out motor impulse commands






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






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






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






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






34. Holds the lens in place






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






36. Having two copies of each chromosomes in most cells (except the gametes) - e.g. most mammals






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






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






39. Symptom of narcolepsy - irresistible urge to






40. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






41. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






42. Is an oversensitivity to dopamine (D2)






43. 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






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






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






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






47. Moving forward






48. Controls sexual activity; lesions inhibit sexual behavior; stimulation increases aggressive sexual behavior






49. Regulates body temperature






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