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. Divided into diencephalon and telencephalon






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






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






4. Provide myelin in peripheral nervous system






5. Organizational and activational






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






7. Incredible rage easily provoked when cerebral cortex is removed






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






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






10. 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






11. Provide myelin in central nervous system






12. 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






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






14. An amino acid - most abundant inhibitory neurotransmitter






15. Protects the brain by making it difficult for toxic substances to pass from the blood into the brain - since blood vessel cells in the brain are tightly packed






16. 16 hours of sleep a day - 6 hours






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






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






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






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






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






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






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






24. Outer half-inch of cerebral hemispheres; - sensory and intellectual functions; - split into frontal - occipital - parietal - temporal lobes; - 90% is neocortex (new in evolution - 6 layers cortex) - 10% < 6 layers and more primitive






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






26. Made up of brain and spinal cord






27. Beginning of neuron (dendrites)






28. 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






29. An amino acid - most abundant excitatory neurotransmitter.






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






31. 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






32. Consists of myelencephalon - metencephalon - and reticular formation






33. Fissures seen on cortex surface






34. Linked to pleasure and analgesia; can be endogenous (opioid peptides) or exogenous (morphine or heroin) - Exogenous endorphine are highly addictive






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






36. Inactivated state of a neuron






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






38. Bumps seen on cortex surface






39. End of a neuron (terminal buttons)






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






41. Where soma and axon connect






42. Of mesencephalon - vision and hearing






43. Present in fast-acting - directed synapses






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






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






46. Connections between brain and spine






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






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. Between myelin sheath - help send impulse down axon






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