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






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






3. 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






4. Of cerebral cortex - responsible for vision






5. 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






6. Beginning of neuron (dendrites)






7. Provide myelin in peripheral nervous system






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






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






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






11. Of diencephalon - channels sensory information to cerebral cortex






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






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






14. Bundles of axon - Nerve fiber






15. An amino acid - most abundant inhibitory neurotransmitter






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






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






18. Gray matter - white matter






19. (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






20. Inner core of spine - cell bodies and dendrites






21. Consists of limbic system - hippocampus - amygdala - cingulate gyrus






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






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






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






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






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






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






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






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






30. Of pituitary - activates thyroid






31. PNS fibers that run towards CNS






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






33. Present in fast-acting - directed synapses






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






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






36. Connections between brain and spine






37. Consists of myelencephalon - metencephalon - and reticular formation






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






39. 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






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






41. Between myelin sheath - help send impulse down axon






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






43. End of a neuron (terminal buttons)






44. Of mesencephalon - vision and hearing






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






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






47. 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)






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






49. Of pituitary - regulate water levels in body and therefore BP






50. Provide myelin in central nervous system
