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. Incredible rage easily provoked when cerebral cortex is removed






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






3. Or just synapse - the space between 2 neurons where they communication






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 Broca'S area - in left frontal lobe; can understand speech but has difficulty speaking (slow - laborious - omits words)

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






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






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






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






10. Bumps on the brainstem - controls auditory reflexes






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






12. Made of thalamus and hypothalamus






13. 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






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






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






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






17. 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






18. 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






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






20. Gray matter - white matter






21. Beginning of neuron (dendrites)






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






23. 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






24. Once minimum threshold is met - intensity always the same regardless of amount of stimulation






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






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






27. Contain synaptic vessels that hold neurotransmitters






28. Chemicals that stimulate nearby cells






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






30. Divided into diencephalon and telencephalon






31. 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






32. Occur during specific periods in development - permanent or long-lasting effects; - presence of H-Y antigen in development causes fetus to develop into a male - absence to female; - androgens in males and estrogen in females causes secondary sex cha






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






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






35. Transmits impulses of neuron - bundles of these are nerve fibers (white matter); the wider nerve fiber - the faster its conduction






36. For female - the onset of the menstrual cycles - occurs during puberty






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






38. Consists of myelencephalon - metencephalon - and reticular formation






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






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






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






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






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






44. Of cerebral cortex - responsible for vision






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






46. Connections between brain and spine






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






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






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






50. Pathway that runs to and from CNS
