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. Tremors - rigidity of limbs - poor balance and difficulty initiating movements

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






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






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






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






6. Functions in metabolism (carbohydrate - protein - lipid) and in the endocrine system'S salt/water balance - produces the hormones cortisol and aldosterone






7. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






8. Opening in the iris; dilates and contracts allowing different levels of light in






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






10. Symptom of narcolepsy; complete paralysis that occurs while AWAKE/conscious; will suddenly fall to floor paralyzed for a few minutes






11. Oculomotor Nerve - moves eye pupil






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






13. 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






14. Occurs when their is damage to the septal area and results in unchecked aggressive and vicious behavior






15. A sensory organ that detects the presence of certain chemicals - especially when a liquid is actively sniffed; mediates the effects of some pheromones






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






17. 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






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






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






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






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






22. 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

23. Maintains balance/posture and coordinates body movements






24. Cumulative effects of repeated stimulation from a presynaptic neuron






25. The synchronization of the menstrual or estrous cycles of a group of females - which occurs only in the presence of a pheromone in a male'S urine






26. Hormones that reduce pain






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






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






29. Acetylcholine - glutamate - gamma-aminobutyric acid - dopamine - serotonin - norepinephrine - endorphin






30. Cornea - aqueous humor - pupil - lens - vitreous humor - retina






31. 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






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






33. Pleasure center of the brain; discovered by Olds & Milner






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






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






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






37. Holds the lens in place






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






39. Supernormal






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






41. Vision: protrusions on top of the midbrain; part of visual system






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






43. A drug that facilitates the effects of a particular neurotransmitter on the postsynaptic cell






44. Vestibulocochlear Nerve - hearing and balance






45. Associated with (spoken) language reception/comprehension - memory processing - and emotional control; contains Wernicke'S area and the auditory cortex






46. Includes comparative (evolution/genetics/animal behavior/ethology) and behavioral regulation






47. Is found in PTSD/CPTSD patients and persons exposed to chronic stress






48. Fluid filled cavities in the middle of the brain - linking to the spinal canal that runs down the middle of the spinal cord; this fluid is cerebrospinal fluid






49. Is regulated by the hypothalamus






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