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. Dysfunction in certain cortical association area - inability to write






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






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






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






5. 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






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






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






8. Of cerebral cortex - responsible for somatosensory system






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






10. Low-amplitude and fast -frequency alpha waves






11. Fissures seen on cortex surface






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






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






14. 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






15. Of mesencephalon - vision and hearing






16. An amino acid - most abundant excitatory neurotransmitter.






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






18. Present in fast-acting - directed synapses






19. 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






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






21. Covers whole neuron - selective permeability - sometimes lets ions (positive charge) through






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






23. Associated with changes in hormone levels throughout the month - estradiol - progesterone - luteinizing hormone - follicle stimulating hormone






24. Where soma and axon connect






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. Beginning of neuron (dendrites)






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






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






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






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






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






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






33. An amino acid - most abundant inhibitory neurotransmitter






34. Inactivated state of a neuron






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






36. Provide myelin in central nervous system






37. Dysfunction in certain cortical association area - language disorder from damage to Broca'S area - in left frontal lobe; can understand speech but has difficulty speaking (slow - laborious - omits words)

38. Bumps on the brainstem - controls auditory reflexes






39. Chemicals that stimulate nearby cells






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






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






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






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






44. Bundles of axon - Nerve fiber






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






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






47. Made up of brain and spinal cord






48. Comprise two classes of neurotransmitters - indolamines and catecholamines






49. Of mesencephalon - rest of reticular formation; Also involved in the sensorimotor system - analgesic effect of opiates






50. 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)
