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






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






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






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






5. Beginning of neuron (dendrites)






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






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 pituitary - stress hormone - increases androgen and cortisol production






9. Where soma and axon connect






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






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






12. Present in fast-acting - directed synapses






13. 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






14. Organizational and activational






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






16. Comprise two classes of neurotransmitters - indolamines and catecholamines






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






18. Consists of myelencephalon - metencephalon - and reticular formation






19. Incredible rage easily provoked when cerebral cortex is removed






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






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






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






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






24. 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






25. Bumps seen on cortex surface






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






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






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






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






30. Of diencephalon - channels sensory information to cerebral cortex






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






32. 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






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






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






35. Of telencephalon - links brain areas dealing with emotion and decisions






36. Midbrain; contains tectum and tegmentum






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






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






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






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






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






42. Of pituitary - activates thyroid






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






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






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






46. Contain synaptic vessels that hold neurotransmitters






47. Provide myelin in central nervous system






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






49. Gray matter - white matter






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