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. Used to implant electrodes into animals' brains in experiments






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






3. Divided into diencephalon and telencephalon






4. 16 hours of sleep a day - 6 hours






5. Aka cell body. largest central portion - and make up gray matter - has a nucleus that directs neuron'S activity






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






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






8. 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






9. Of cerebral cortex - responsible for somatosensory system






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






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






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






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






14. 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)


15. An amino acid - most abundant excitatory neurotransmitter.






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






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






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






19. Holds neurotransmitters






20. Of diencephalon - channels sensory information to cerebral cortex






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






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






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






24. Of mesencephalon - vision and hearing






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






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






27. Made of thalamus and hypothalamus






28. Made up of brain and spinal cord






29. Where soma and axon connect






30. Fissures seen on cortex surface






31. An amino acid - most abundant inhibitory neurotransmitter






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






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






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






35. Of Hindbrain - aka medulla; Mainly controls for reflexes - but also controls sleep - attention - movement






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






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






38. Bumps on the brainstem - controls visual reflexes






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






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






41. Low-amplitude and fast -frequency alpha waves






42. Of pituitary - activates thyroid






43. Inner core of spine - cell bodies and dendrites






44. Midbrain; contains tectum and tegmentum






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






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






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






48. Gray matter - white matter






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






50. 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
