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. Comprise two classes of neurotransmitters - indolamines and catecholamines






2. Fissures seen on cortex surface






3. Of cerebral cortex - responsible for vision






4. Bundles of axon - Nerve fiber






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






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






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






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






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






10. 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






11. Provide myelin in central nervous system






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






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. 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)

15. Inner core of spine - cell bodies and dendrites






16. Consists of myelencephalon - metencephalon - and reticular formation






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






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






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






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






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






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






23. Organizational and activational






24. PNS fibers that run towards CNS






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






26. Of pituitary - activates thyroid






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






28. Made up of brain and spinal cord






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






30. 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 -->






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






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






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






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






35. Present in fast-acting - directed synapses






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






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






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






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






40. An amino acid - most abundant excitatory neurotransmitter.






41. Bumps seen on cortex surface






42. Of telencephalon - controls emotional reactions such as fear and anger






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






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






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






46. 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






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






48. End of a neuron (terminal buttons)






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






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