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






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






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






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






5. 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)

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


6. Chemicals that stimulate nearby cells






7. 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






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. Connections between brain and spine






11. 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






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






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






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






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






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






17. Low-amplitude and fast -frequency alpha waves






18. Of diencephalon - channels sensory information to cerebral cortex






19. 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






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






21. Consists of myelencephalon - metencephalon - and reticular formation






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






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






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






25. 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






26. Made up of brain and spinal cord






27. Pathway that runs to and from CNS






28. Fissures seen on cortex surface






29. Of pituitary - stress hormone - increases androgen and cortisol production






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






31. End of a neuron (terminal buttons)






32. Organizational and activational






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






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






35. 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






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






37. Comprise two classes of neurotransmitters - indolamines and catecholamines






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






39. Of cerebral cortex - responsible for vision






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






41. Provide myelin in central nervous system






42. Provide myelin in peripheral nervous system






43. Time after a neuron fires which it cannot respond to stimulation






44. Contain synaptic vessels that hold neurotransmitters






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






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






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






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






49. Bundles of axon - Nerve fiber






50. Where soma and axon connect
