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. Fissures seen on cortex surface






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






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






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






5. Chemicals that stimulate nearby cells






6. PNS fibers that run towards CNS






7. Present in fast-acting - directed synapses






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






9. 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 -->






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






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






12. Provide myelin in peripheral nervous system






13. Made of thalamus and hypothalamus






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






15. 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






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






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






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






19. Inactivated state of a neuron






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






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






22. Process in which neural pathways are connected and then some die out (children go through these process)






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






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






25. A type of cell that help support neurons; oligodendrocytes and Schwann cells






26. Holds neurotransmitters






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






28. Of cerebral cortex - responsible for vision






29. Bumps on the brainstem - controls visual reflexes






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






31. 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)

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






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






34. Inner core of spine - cell bodies and dendrites






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






36. Bumps seen on cortex surface






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






38. An amino acid - most abundant inhibitory neurotransmitter






39. Where soma and axon connect






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






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






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






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






44. 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






45. Incredible rage easily provoked when cerebral cortex is removed






46. Of pituitary - activates thyroid






47. Gray matter - white matter






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






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






50. Protects the brain by making it difficult for toxic substances to pass from the blood into the brain - since blood vessel cells in the brain are tightly packed
