When measuring brain functioning with _____________, researchers use a geodesic sensor net to hold interconnected electrodes in place.
A) the EEG
B) fMRI
C) PET
D) NIRS

Question

Quizplus · Accepted Answer

The method described in the question (use of a geodesic sensor net to hold interconnected electrodes in place) is most commonly used for EEG (electroencephalography) measurements, therefore the best choice is A. FMRI (functional magnetic resonance imaging) measures blood flow and PET (positron emission tomography) measures metabolic activity, and do not require a sensor net. NIRS (near-infrared spectroscopy) uses optode probes that are placed on the scalp, but not in a geodesic sensor net.
