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. Bundles of axon - Nerve fiber






2. Of cerebral cortex - responsible for somatosensory system






3. The process after a neurotransmitter has done its job - it is reabsorbed by the presynaptic cell






4. Fissures seen on cortex surface






5. Of diencephalon - controls autonomic nervous system biological motivations (hunger - thirst) and pituitary gland






6. 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)

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


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






8. Time after absolute refractory period - neuron can fire but needs a much stronger stimulus






9. Controlled by hypothalamus - regulation of hormones in the body - The 'master gland' of the endocrine/hormone system






10. Organizational and activational






11. Chambers filled with cerebrospinal fluid that insulate brain from shock






12. Consists of myelencephalon - metencephalon - and reticular formation






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






14. The basic unit of the nervous system - Consist of: Dentrites - cell body (soma) - axon hillock - axon - myelin sheath - nodes of Ranvier - Terminal buttons - cell membrane - synapse - glial cells






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






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






17. Of cerebral cortex - responsible for vision






18. Associated with changes in hormone levels throughout the month - estradiol - progesterone - luteinizing hormone - follicle stimulating hormone






19. End of a neuron (terminal buttons)






20. Measures oxygen flow in different brain areas - used most in cognitive psych to measure activity in different brain regions during certain tasks






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






22. Anytime during adulthood - short periods - often transient or reversible (current/recent circulation); - menstrual cycle (estradiol - progesterone - luteinizing hormone (LH) - follicle stimulating hormone (FSH)); - LH and FSH in females regulate ovum






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






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






25. PNS fibers that run away from CNS (to cause effect the brain wants)






26. Occur during specific periods in development - permanent or long-lasting effects; - presence of H-Y antigen in development causes fetus to develop into a male - absence to female; - androgens in males and estrogen in females causes secondary sex cha






27. Of mesencephalon - vision and hearing






28. Of pituitary - stress hormone - increases androgen and cortisol production






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






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






31. 16 hours of sleep a day - 6 hours






32. ANS - recuperation after arousal (decrease HR - BP - respiration)






33. Control large voluntary muscle movements - Their degeneration is related to motor dysfunction in Parkinson'S and Huntington'S






34. Inactivated state of a neuron






35. Bumps on the brainstem - controls auditory reflexes






36. Dysfunction in certain cortical association area - difficulty processing sensory information






37. Gray matter - white matter






38. comprises 50% of total sleep at birth - decreases to 25% - 20% sleep time spent in this type of sleep - Interspersed with non-REM every 30-40min - where dreams are experience - characterized by neural desynchrony - also known as paradoxical sleep -->






39. 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






40. 4-6 complete ones - each about 90 minutes - early in the night most time in stage 3 and 4 - 2 and REM sleep predominate later






41. Holds neurotransmitters






42. Of hindbrain - has pons(connects brain parts to spine) and cerebellum(controls muscle coordination - balance - posture)






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






44. Contain synaptic vessels that hold neurotransmitters






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






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






47. Made of thalamus and hypothalamus






48. 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






49. Provide myelin in central nervous system






50. Bumps seen on cortex surface
