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. Projects to ventral tegmental area






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






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






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






5. A 90-minute activity cycle occurs throughout the day as well as throughout sleep (in humans) waxing and waning alertness controlled by a biological clock in the caudal brainstem that also controls cycles of REM and slow-wave sleep






6. Glandular system control center - produces the hormones oxytocin and antidiuretic; functions in both the nervous system and endocrine sytem - In the forebrain - regulates motivated behaviors (eating - drinking - aggression - sexual behavior






7. Decreasing effects of a medication due to repeated administration






8. 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






9. Found in the ventricles and spinal canal






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






11. Has neurons for reflexes






12. Trigerminal Nerve - face sensation






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






14. Acquired language disorders - usually caused by damage in the left hemisphere; includes Broca'S: (left frontal lobe damage) and Wernickes'S (left temporal/parietal damage)






15. 'Roof'






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






17. 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






18. Self-dissolving






19. Contains delta activity - stages III and IV






20. In the limbic system - is a fiber bundle - connects hippocampus with stuff (including the mammillary bodies of the hypothalamus)






21. 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






22. 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






23. The maintenance of water balance in the body






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






25. The increase in REM sleep seen after a period of REM sleep deprivation






26. Absolute; relative






27. 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






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






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






30. Facial Nerve - moves face and salivates






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






32. 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






33. Occurs during the deepest stages of slow-wave sleep; regular - synchronous electrical activity of less than 4 Hz






34. Binding of drug to receptor site that doesn'T interfere with the principal ligand






35. Occurs at the onset of puberty; a hypothalamic hormone that stimulates the pituitary gland to secrete gonadotropin






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






37. In the posterior frontal lobe - contains the somatosensory cortex (touch - pressure - temperature - pain)






38. Binding of a drug to a receptor site that does not interfere with the binding site for the principal ligand






39. Include tolerance (possible withdrawal) and sensitivity






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






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






42. 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






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






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






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






46. Means 'Savory' in Japanese and is a taste receptor found on the tongue; activated by glutamate present in meats - cheese and other protein heavy foods






47. Produce drowsiness and sleepiness






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






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






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