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






2. Of telencephalon - involves in memory- transfer STM into LTM - - new neurons can form in adult mammalian brain






3. Made up of brain and spinal cord






4. PNS - interacts with external environment by controlling voluntary movements of striated muscles






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






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






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






8. Beginning of neuron (dendrites)






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






10. Pathway that runs to and from CNS






11. 16 hours of sleep a day - 6 hours






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






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






14. Increase in males during puberty causes genitals to matures and secondary sex characteristics to develop - example: testosterone






15. Fatty - insulating sheath on some axons for faster conduction of axon impulses






16. Inner core of spine - cell bodies and dendrites






17. Gray matter - white matter






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






19. An amino acid - most abundant inhibitory neurotransmitter






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






21. Incredible rage easily provoked when cerebral cortex is removed






22. Outer covering of spine - nerve fibers - axon bundles - myelin sheathing






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






24. Occurs when people deprived of REM sleep - compensate by spending more time in REM sleep later in the night






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






26. 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






27. PNS fibers that run towards CNS






28. Of cerebral cortex - responsible for somatosensory system






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






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






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






32. Consists of limbic system - hippocampus - amygdala - cingulate gyrus






33. Provide myelin in central nervous system






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






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






36. Of pituitary - activates thyroid






37. Organizational and activational






38. Comprise two classes of neurotransmitters - indolamines and catecholamines






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






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






41. Inactivated state of a neuron






42. Aka cell body. largest central portion - and make up gray matter - has a nucleus that directs neuron'S activity






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






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






45. Present in fast-acting - directed synapses






46. Dysfunction in certain cortical association area - language disorder from damage to Wernicke'S area - in left temporal lobe; can speak but doesn'T understand how to correctly choose words (fluent but nonsensical)

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


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






48. Include dopamine - lack of dopamine linked with Parkinson'S - excess dopamine is linked with schizophrenia - dopamine is also involved in feelings of reward and therefore addiction






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






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