113. Small metal disks are pasted onto Miranda’s scalp and connected by wire to a machine that translates the electrical energy from her brain into wavy lines on a moving piece of paper. From this description, it is evident that Miranda’s brain is being studied through the use of___________.a)a CT scanIncorrect. CT scans take computer-controlled X-rays of the brain. b)functional magnetic resonance imagingc)a microelectroded)an electroencephalogram (EEG)Correct. Electroencephalograms record brain wave patterns. ANS: d, p. 62, A, LO=2.6, (2) SG 114. Which of the following is a machine designed to record the brain wave patterns produced by electrical activity of the surface of the brain?96ScholarStock
= .29115. Which equipment is used to monitor brain waves?= .37116. Which of the following is a brain-imaging method in which radioactive sugar is injected into the subject and a computer compiles a color-coded image of the activity of the brain?117. Libby’s physician refers her to a medical center in order to have the biochemical activity in her brain analyzed. She is given an injection of a radioactive glucose-like substance and then is told to lie down with her head in a scanner. The technique being used is ______________.a)positron emission tomographyCorrect. PET involves injecting a radioactive glucose into the patient. b)functional magnetic resonance imagingIncorrect. fMRI does not involve injecting the patient with glucose.c)microelectrode recording.d)an electroencephalogram (EEG)ANS: a, p. 63, A, LO=2.6, (2) 118. Marika needs to have a neuroimaging test that will track the activity of her brain, along with changes in her brain oxygen levels. Which of the following offers an alternative to PET scans, with the advantage of using radioactive tracers that are easier to monitor?= .24
