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






2. 16 hours of sleep a day - 6 hours






3. Provide myelin in peripheral nervous system






4. (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






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






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






7. Dysfunction in certain cortical association area - difficulty processing sensory information






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






9. Low-amplitude and fast -frequency alpha waves






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






11. Inactivated state of a neuron






12. Present in fast-acting - directed synapses






13. Increase in female during puberty causes genitals to matures and secondary sex characteristics to develop






14. 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






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






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






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






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






19. Released from the pituitary and facilitates birth and breast feeding - also involved in pair bonding (mother to child or romantic partners) -






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






21. Bundles of axon - Nerve fiber






22. Of pituitary - activates thyroid






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






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






25. Bumps on the brainstem - controls auditory reflexes






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






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






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






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






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






31. Holds neurotransmitters






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






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






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






35. 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






36. Increase in males during puberty causes genitals to matures and secondary sex characteristics to develop - example: testosterone






37. Of cerebral cortex - responsible for somatosensory system






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






39. Time after absolute refractory period - neuron can fire but needs a much stronger stimulus






40. Organizational and activational






41. Bumps on the brainstem - controls visual reflexes






42. Incredible rage easily provoked when cerebral cortex is removed






43. An amino acid - most abundant inhibitory neurotransmitter






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






45. Consists of myelencephalon - metencephalon - and reticular formation






46. Gray matter - white matter






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






48. Pathway that runs to and from CNS






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






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