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. 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






2. Stage 3 (less sleep spindles) & 4 non-REM sleep - high-amplitude and low-frequency - deepest level of sleep






3. Made of thalamus and hypothalamus






4. 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






5. Comprise two classes of neurotransmitters - indolamines and catecholamines






6. Midbrain; contains tectum and tegmentum






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






8. Of Hindbrain - aka medulla; Mainly controls for reflexes - but also controls sleep - attention - movement






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






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






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






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






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






14. Of mesencephalon - vision and hearing






15. Made up of brain and spinal cord






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






17. Connections between brain and spine






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






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






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






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






22. Like neurotransmitters but cause long-term changes in postsynaptic cell






23. Low-amplitude and fast -frequency alpha waves






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






25. 16 hours of sleep a day - 6 hours






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






27. Provide myelin in peripheral nervous system






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






29. An amino acid - most abundant excitatory neurotransmitter.






30. Contain synaptic vessels that hold neurotransmitters






31. Organizational and activational






32. Inactivated state of a neuron






33. End of a neuron (terminal buttons)






34. Of cerebral cortex - responsible for somatosensory system






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






36. Bumps on the brainstem - controls auditory reflexes






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






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






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






40. Stage 1 & 2 non-REM sleep (with sleep spindles) - lower-amplitude and slower frequency waves






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






42. 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






43. Increase in female during puberty causes genitals to matures and secondary sex characteristics to develop






44. For female - the onset of the menstrual cycles - occurs during puberty






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






46. An amino acid - most abundant inhibitory neurotransmitter






47. Consists of myelencephalon - metencephalon - and reticular formation






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






49. Of cerebral cortex - responsible for vision






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