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. 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






2. Short bursts of waves 12-14 Hz that occur 2-5 times a minute during stages 1-4 of sleep; most characteristic of sleep Stage II; some believe sleep spindles are involved in keeping one asleep (decline in older people)






3. Symptom of narcolepsy - irresistible urge to






4. Olfactory Nerve - smell






5. Important to motor system






6. Supernormal






7. 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






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






9. If a synapse is active at about the same time that a postsynaptic neuron is active - that synapse will be strengthened






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






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






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






13. Trochlear Nerve - moves eye






14. Similarity of alleles for a trait in an organism (i.e. heterozygous or homozygous)






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






16. Occurs when a neuron is hyperpolarized and characterized by sufficient strength of stimulation triggering a new action potential






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






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






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






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






21. Relays nerve impulses - processes sensory impulses - reflex behavior and contains nerve cell bodies






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






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






24. Colored part of the eye






25. The visual image of the world on the retina






26. Some brain communications are with the same side of the body






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






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






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






30. ...






31. Produce drowsiness and sleepiness






32. 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






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






34. Hypoglossal Nerve - moves the tongue






35. Dorsal part of midbrain; includes the superior and inferior colliculi






36. Glossopharyngeal Nerve - taste swallow






37. An ovary or teste






38. Occur in amacrine - bipolar and horizontal cells; govern/encompass the opponent-process level of color vision






39. Causes mesolimbic dopamine hyperactivity; etiology of schizophrenia






40. Holds the lens in place






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






42. Is an oversensitivity to dopamine (D2)






43. Related to plasticity - the term Lashley used to describe different parts of the cortex being interchangeable in their roles in learning






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






45. Is used to treat Parkinson'S Disease






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






47. Made from within - natural






48. Phantom limb pain - hypnotic induction and the success rate of placebo treatments






49. Synchronized EEG activity during its deeper stages






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