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






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






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






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






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






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






7. Bundles of axon - Nerve fiber






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






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






10. Changes in a nerve cell'S charge as the result of stimulation - 2 forms: excitatory postsynaptic potential and inhibitory postsynaptic potential






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






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






13. Where soma and axon connect






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






15. Bumps on the brainstem - controls auditory reflexes






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






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






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






19. PNS - interacts with internal environment - - Responsible for the 'fight or flight' response - - It controls the involuntary functions including movement of smooth muscles - digestion - blood circulation - breathing






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






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






22. 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


23. Released at neuromuscular junction to cause contraction of skeletal muscles - also involved in parasympathetic nervous system






24. Bumps on the brainstem - controls visual reflexes






25. Covers whole neuron - selective permeability - sometimes lets ions (positive charge) through






26. Time after a neuron fires which it cannot respond to stimulation






27. Made up of brain and spinal cord






28. Between myelin sheath - help send impulse down axon






29. Inner core of spine - cell bodies and dendrites






30. 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






31. Of diencephalon - channels sensory information to cerebral cortex






32. Incredible rage easily provoked when cerebral cortex is removed






33. Organizational and activational






34. Positron emission tomography - scans glucose metabolism to measure activity in various brain regions






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






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






37. Transmits impulses of neuron - bundles of these are nerve fibers (white matter); the wider nerve fiber - the faster its conduction






38. Comprise two classes of neurotransmitters - indolamines and catecholamines






39. 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






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






41. Of cerebral cortex - responsible for vision






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






43. Present in fast-acting - directed synapses






44. Made up of somatic nervous system and autonomic nervous system






45. End of a neuron (terminal buttons)






46. 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






47. Made of thalamus and hypothalamus






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






49. PNS fibers that run towards CNS






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