GRE Psychology: Physiological/behavioral Neuroscience 1

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. Neuron branches - receive impulses - branching patterns change throughout life






2. In females - regulate the development of ovum and trigger ovulation - In males - regulate the development of sperm cells and the production of testosterone






3. REM-sleep - low-amplitude and fast-frequency waves that characterize waking states






4. Inactivated state of a neuron






5. Stage 0 & 1 non-REM sleep - low-amplitude and fast-frequency waves






6. Jumping from one node of Ranvier to the next due to insulation by myelin sheath






7. Of pituitary - activates thyroid






8. Made of thalamus and hypothalamus






9. Overeating with no satiation of hunger; leads to obesity; damage to ventromedial region of hypothalamus






10. Dysfunction in certain cortical association area - inability to read






11. Dysfunction in certain cortical association area - language disorder from damage to Broca'S area - in left frontal lobe; can understand speech but has difficulty speaking (slow - laborious - omits words)

12. ANS - controls arousal mechanisms (blood circulation - pupil dilation - threat and fear response) - Lie detector test relies on the premise -->lying activates the sympathetic nervous system and cause things like (increase heart rate - blood pressure






13. Released from the pituitary and facilitates birth and breast feeding - also involved in pair bonding (mother to child or romantic partners) -






14. Depolarization - + from outside allowed into cell - increase firing






15. Hyperpolarization - + let out - - compared to outside - decrease firing






16. Base in hindbrain - rest in midbrain; oldest brain area; Controls alertness - thirst - sleep - involuntary muscles (i.e. heart)






17. Or just synapse - the space between 2 neurons where they communication






18. An amino acid - most abundant inhibitory neurotransmitter






19. Outer half-inch of cerebral hemispheres; - sensory and intellectual functions; - split into frontal - occipital - parietal - temporal lobes; - 90% is neocortex (new in evolution - 6 layers cortex) - 10% < 6 layers and more primitive






20. Increase effects of a neurotransmitter (e.g. selective serotonin reuptake inhibitors [for depression] increase serotonin activity)






21. Fast frequency bursts of brain activity - inhibits processing to keep tranquil state






22. Takes about half an hour; (0) prelude to sleep - neural synchrony; alpha waves; person is relaxed and drowsy - closes eye; (1) Eyes begin to roll. alpha waves give way to irregular theta waves; loses responsiveness to stimuli - experiences fleeting t






23. Of telencephalon - links brain areas dealing with emotion and decisions






24. Gray matter - white matter






25. Of telencephalon - structures around the brainstem involved in 4Fs (fleeing - feeding - fighting - and fornicating)






26. Of diencephalon - channels sensory information to cerebral cortex






27. Consists of myelencephalon - metencephalon - and reticular formation






28. Beginning of neuron (dendrites)






29. Midbrain; contains tectum and tegmentum






30. Bumps on the brainstem - controls visual reflexes






31. Of telencephalon - controls emotional reactions such as fear and anger






32. Inner core of spine - cell bodies and dendrites






33. Dysfunction in certain cortical association area - inability to organize movement






34. Dysfunction in certain cortical association area - inability to write






35. A type of cell that help support neurons; oligodendrocytes and Schwann cells






36. Include serotonin - lack of serotonin is linked with depression






37. Of cerebral cortex - controls speech (Broca'S area) - reasoning - problem solving






38. Decrease effects of a neurotransmitter (e.g. botox is an acetylecholine antagonist that decreases muscle activity)






39. Of pituitary - regulate water levels in body and therefore BP






40. Divided into diencephalon and telencephalon






41. Presence during development causes a fetus to develop into a male (absence cause the fetus to develop into a female)






42. Once minimum threshold is met - intensity always the same regardless of amount of stimulation






43. Where soma and axon connect






44. Process in which neural pathways are connected and then some die out (children go through these process)






45. Areas on cortex that correspond to certain functions; - the larger the area - the more sensitive and highly accessed the function - Damage to a particular area would result in certain dysfunction






46. Chemicals that stimulate nearby cells






47. Holds neurotransmitters






48. Of mesencephalon - rest of reticular formation; Also involved in the sensorimotor system - analgesic effect of opiates






49. Tough connective tissues that cover/protect brain and spinal cord






50. Low-amplitude and fast -frequency alpha waves
