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 visual image of the world on the retina






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






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






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






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






6. Is characteristic of indirect antagonists






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






8. ...






9. Optic Nerve - sight






10. Contains receptors to detect when the body needs food or fluids; the hunger center; lesions lead to aphagia






11. 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






12. Actually are two kinds: monochorionic and dichorionic (blastocyst splis into two before day 4)






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






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






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






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






17. 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






18. Receptors whose activation directly affects potassium or chloride ion channels in the neuron - (many drugs of abuse substitute for natural GABA- alcohol - benzos - barbituates






19. Lens changes initiated by the ciliary muscles to change the shape of the lens in order to focus image on the retina






20. 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






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






22. Completely disactivates the prefrontal cortex (PFC); due to high levels of norepinephrine (NE)






23. Adenine - Guanine - Thymine - Cytosine






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






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






26. Include tolerance (possible withdrawal) and sensitivity






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






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






29. Supernormal






30. Self-dissolving






31. Cumulative effects of repeated stimulation from a presynaptic neuron






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






33. Olfactory Nerve - smell






34. Abducens Nerve - moves eye






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






36. An area that combines input from diverse brain regions






37. Projects to ventral tegmental area






38. Transparent substance between lens and retina






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






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






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






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






43. Thymoleptics = relieves mania of bipolar disorder (lithium carbonate - valproic acid - carbamazepine)






44. Bunch of dopaminergic neurons starting in the substantia nigra and ending in the neostriatum






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






46. Vestibulocochlear Nerve - hearing and balance






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






48. Combines input from diverse brain regions; receives sensory information/sends motor impulses






49. Hormones that reduce pain






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