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. 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






2. Facial Nerve - moves face and salivates






3. Is a peptide neurotransmitter and a natural painkiller and antianxiety






4. Controls sexual activity






5. The midbrain; a region that surrounds the cerebral aqueduct; includes tectum and the tegmentum






6. Sleepwalking - sleep talking






7. A single - unfertilized cell created during conception; the combined egg + sperm






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






9. The maintenance of water balance in the body






10. Termination of pregnancy by the odor of a pheromone in the urine of a male other than the one that impregnated the female; first observed in mice






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






12. 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






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






14. Optic Nerve - sight






15. Contains delta activity - stages III and IV






16. 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

17. Has neurons for reflexes






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






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






20. Those biological considerations which are DISTANT; Evolutionary Psychology - Comparative Psychology - Ethology






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






22. In the CNS - is an amino acid that stabilizes neural activity






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






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






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






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






27. Research indicates that the expressing of negative emotions is associated with increased immune function; inhibiting negative emotions with decreasing immune function






28. Functions as both a hormone and a neurotransmitter in the brain






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






30. AKA the striate cortex - located at the back of the brain - and contains the visual cortex






31. 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






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






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






35. Lesions to this brain structure that is crucial to memory will produce anterograde amnesia






36. Located in the forebrain - basal ganglia -> movement -speech and other complex behaviors






37. Found in the ventricles and spinal canal






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






39. Is a loss of dopamine cells in the substantia nigra of the basal ganglia; these cells are usually dark (nigra) but in Parkinson'S - the substantia nigra appears white due to cell death

40. Is regulated by the hypothalamus






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






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






43. A behavior that has different forms or occurs with different probabilities or under different circumstances in males than females






44. Affect sex characteristics/development and produce estrogen/progesterone (in females - ovaries) and testosterone (in male - testes)






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






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






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






48. Damage to this are causes clumsiness and loss of balance






49. The viscous substance between cornea and lens






50. Junction of the sagittal and coronal sutures of the skull; often used as a reference point for stereotaxic brain surgery
