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






2. Provide myelin in central nervous system






3. Bumps on the brainstem - controls auditory reflexes






4. Where soma and axon connect






5. An amino acid - most abundant excitatory neurotransmitter.






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






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






8. Include dopamine - lack of dopamine linked with Parkinson'S - excess dopamine is linked with schizophrenia - dopamine is also involved in feelings of reward and therefore addiction






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






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






11. Low-amplitude and fast -frequency alpha waves






12. Connections between brain and spine






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






14. Made of thalamus and hypothalamus






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






16. comprises 50% of total sleep at birth - decreases to 25% - 20% sleep time spent in this type of sleep - Interspersed with non-REM every 30-40min - where dreams are experience - characterized by neural desynchrony - also known as paradoxical sleep -->






17. Gray matter - white matter






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






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






20. Comprise two classes of neurotransmitters - indolamines and catecholamines






21. Fissures seen on cortex surface






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






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






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






25. 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)


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






27. Contain synaptic vessels that hold neurotransmitters






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






29. An amino acid - most abundant inhibitory neurotransmitter






30. Holds neurotransmitters






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






32. 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






33. Bumps seen on cortex surface






34. Of mesencephalon - vision and hearing






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






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






37. 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






38. Between myelin sheath - help send impulse down axon






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






40. Of diencephalon - channels sensory information to cerebral cortex






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






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






43. PNS fibers that run towards CNS






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






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






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






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






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






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






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