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. PNS fibers that run towards CNS






2. Include serotonin - lack of serotonin is linked with depression






3. Inactivated state of a neuron






4. Of pituitary - activates thyroid






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






6. Hyperpolarization - + let out - - compared to outside - decrease firing






7. 16 hours of sleep a day - 6 hours






8. 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






9. ANS - controls arousal mechanisms (blood circulation - pupil dilation - threat and fear response) - Lie detector test relies on the premise -->lying activates the sympathetic nervous system and cause things like (increase heart rate - blood pressure






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






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






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






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






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






15. Comprise two classes of neurotransmitters - indolamines and catecholamines






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






17. Bumps seen on cortex surface






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






19. Of mesencephalon - vision and hearing






20. 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






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






22. Of cerebral cortex - responsible for somatosensory system






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






24. An amino acid - most abundant inhibitory neurotransmitter






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






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






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






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






29. Inner core of spine - cell bodies and dendrites






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






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






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






33. Low-amplitude and fast -frequency alpha waves






34. Beginning of neuron (dendrites)






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






36. Provide myelin in peripheral nervous system






37. 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






38. Between myelin sheath - help send impulse down axon






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






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






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






42. Used to implant electrodes into animals' brains in experiments






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






44. 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






45. Midbrain; contains tectum and tegmentum






46. Chemicals that stimulate nearby cells






47. (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






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






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






50. Bundles of axon - Nerve fiber
