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. Measures brain wave patterns and have made it possible to study waking and sleeping states






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






3. Low-amplitude and fast -frequency alpha waves






4. 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






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






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






7. 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






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






9. Present in fast-acting - directed synapses






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






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






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






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






14. 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






15. Provide myelin in central nervous system






16. Of cerebral cortex - responsible for somatosensory system






17. Pathway that runs to and from CNS






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






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






20. Midbrain; contains tectum and tegmentum






21. Extension of the spine - developed from base to the front






22. Of mesencephalon - vision and hearing






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






24. Where soma and axon connect






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






26. Comprise two classes of neurotransmitters - indolamines and catecholamines






27. Between myelin sheath - help send impulse down axon






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






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






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






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






32. Of pituitary - activates thyroid






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






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






35. Inactivated state of a neuron






36. Made of thalamus and hypothalamus






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






38. Made up of brain and spinal cord






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






40. An amino acid - most abundant excitatory neurotransmitter.






41. Made up of sympathetic nervous system and parasympathetic nervous system






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






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






44. An amino acid - most abundant inhibitory neurotransmitter






45. (1) resting potential - neuron negatively charged - cell membrane does not let ions in; (2) presynaptic cell releases neurotransmitters from terminal buttons; (3) postsynaptic receptors in postsynaptic cells detects neurotransmitter and open ion chan






46. Consists of myelencephalon - metencephalon - and reticular formation






47. Bumps on the brainstem - controls visual reflexes






48. 16 hours of sleep a day - 6 hours






49. Holds neurotransmitters






50. Of cerebral cortex - responsible for hearing - also Wernicke'S area (related to speech)
