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 pituitary - stress hormone - increases androgen and cortisol production






3. Released at neuromuscular junction to cause contraction of skeletal muscles - also involved in parasympathetic nervous system






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






5. Of cerebral cortex - responsible for somatosensory system






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






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






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






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






10. 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






11. End of a neuron (terminal buttons)






12. Chemicals that stimulate nearby cells






13. PNS fibers that run towards CNS






14. Beginning of neuron (dendrites)






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






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






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






18. 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






19. Where soma and axon connect






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






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






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






23. Made up of brain and spinal cord






24. Of diencephalon - channels sensory information to cerebral cortex






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






26. Of telencephalon - structures around the brainstem involved in 4Fs (fleeing - feeding - fighting - and fornicating)






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






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






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






30. Organizational and activational






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






32. Of cerebral cortex - responsible for vision






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






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






35. Consists of myelencephalon - metencephalon - and reticular formation






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






37. Base in hindbrain - rest in midbrain; oldest brain area; Controls alertness - thirst - sleep - involuntary muscles (i.e. heart)






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






39. Overeating with no satiation of hunger; leads to obesity; damage to ventromedial region of hypothalamus






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






41. Bumps on the brainstem - controls visual reflexes






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






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






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






45. Dysfunction in certain cortical association area - language disorder from damage to Wernicke'S area - in left temporal lobe; can speak but doesn'T understand how to correctly choose words (fluent but nonsensical)

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






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






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






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






50. 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
