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. The Lee-Boot effect - Whitten effect - Vandenbergh effect - and the Bruce effect; all mediated by the VNO






2. A drug that opposes/inhibits the effects of a particular neurotransmitter on the postsynaptic cell






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






4. Projects to ventral tegmental area






5. Sleepwalking - sleep talking






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






7. ...






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






9. Has neurons for reflexes






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






11. Produce drowsiness and sleepiness






12. Auditory receptor cells in the cochlea that turn sound vibrations -> neural impulses






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

14. 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






15. A large network of neural tissue located in the central region of the brain stem - from the medulla to the diencephalon






16. Glossopharyngeal Nerve - taste swallow






17. Decreasing effects of a medication due to repeated administration






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






19. Governs eating/drinking (lateral and ventromedial hypothalami) and sexual activity (anterior portion






20. Optic Nerve - sight






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






22. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






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






24. The female reproductive cycle of mammals other than primates






25. Abducens Nerve - moves eye






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






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






28. Activates one of 5 types of receptors in the CNS - cognition - motor activity - reward - muscle tone - sleep - mood - attention - learning -higher level effects of dopamine = D2






29. Found that developmental changes occurring in puberty make the brain more susceptible to the psychotic effects of NDMA antagonist and therefore also related to the emergence of symptoms of schizophrenia






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






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






32. Follow Hering'S Opponent Process of color vision - and only have two types: red-green and yellow-blue; other levels of color vision are tri-chromatic






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






34. 'little net'






35. 'little brain'






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






37. The maintenance of water balance in the body






38. The restorative effect of introducing a new female sex partner to a male that has apparently become 'exhausted' by sexual activity






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






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






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






42. Synchronized EEG activity during its deeper stages






43. Refers to both the somatosensory cortex and motor cortex (they are a little different but very interrelated)






44. 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)






45. Forebrain -band of nerve fibers connecting the two cerebral hemispheres






46. Hormone secreted during the night by the pineal body; role in circadian and seasonal rhythms






47. A region of the visual association cortex located in the extrastriate cortex at the base of the brain that has special face-recognizing circuits (more important in right hemisphere)






48. 'Roof'






49. Vagus Nerve - heart rate and digestion






50. Olfactory Nerve - smell
