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. 'Roof'






2. Colored part of the eye






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






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






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






6. Involved in the effects of odors/pheromones in reproductive behavior - a nucleus that receives olfactory information from the olfactory bulb and accessory olfactory bulb






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






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






9. 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






10. Include tolerance (possible withdrawal) and sensitivity






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






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






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






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






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






16. Is increased in its production by training/experience and therefore - associated with memory






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






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






19. 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)






20. Automatic and rapidly acquired reactions - not attributable to reinforcement or conditioning






21. Found in the ventricles and spinal canal






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






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






24. The visual image of the world on the retina






25. 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






26. Oculomotor Nerve - moves eye pupil






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






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






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






30. Projects to ventral tegmental area






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






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






33. Regulates body temperature






34. An area that combines input from diverse brain regions






35. 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






36. Most pervasive excitatory neurotransmitter in the brain






37. Controls circadian rhythms - produces melatonin (daylight signals go to the eyes to the hypothalamus to the pineal gland)






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






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






40. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






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






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






44. Made from within - natural






45. Increasing effects/effectiveness of a medication due to repeated administration






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






47. 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






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






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






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