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






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






3. Includes the tectum and tegmentum






4. Colored part of the eye






5. Maintains balance/posture and coordinates body movements






6. Associated with defensive and aggressive behavior; lesions produce docility and hypersexual states (Kluver & Bucy)






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






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






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






10. Mechanism whereby neurons make connections to new areas to change their connectivity






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






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






13. Comprised of the hypothalamus - pituitary gland - thyroid gland - parathyroid - the adrenal cortex - the adrenal medulla - the pancreas - the ovaries/testes - pineal gland.






14. Physiologically different from the other four stages of sleep (i.e. the similarity between the summed electrical activity of neurons measured on the scalp (EEG) during REM sleep and during wakefulness






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






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






17. Sleepwalking - sleep talking






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






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






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






21. 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






22. Regulates body temperature






23. Consummatory stimuli - sign stimuli - supernormal stimuli - releaser






24. Bunch of dopaminergic neurons starting in the ventral tegmental area and ending in the nucleus accumbens - amygdala and hippocampus






25. The visual image of the world on the retina






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






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






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






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






30. Self-dissolving






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






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






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






34. Produces acetylcholine. One of the earliest sites of cell death in Alzheimer'S Disease (neurological disorder associated with a deficiency in acetylcholine) is in the basal forebrain






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






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






37. Transparent substance between lens and retina






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






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






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






41. The maintenance of water balance in the body






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






43. Adenine - Guanine - Thymine - Cytosine






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






45. Occurs intermittently during early stages of slow-wave sleep and REM sleep 3.5-7.5 Hz






46. Suggests that dreams are nothing more than the product of random electrical impulses (Hobson & McCarley)






47. A patient who had intact intelligence but an inability to learn/remember anything new (severe anterograde amnesia)






48. 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






49. Begins where spinal cord ends - 3 structures: the medulla - the pons - the cerebellum






50. In the tegmentum (ventral part of midbrain); its neurons connect to caudate nucleus + putamen (in basal ganglia)
