Motor response detection using fiber optics during functional magnetic resonance imaging.
Data acquisition during functional magnetic resonance imaging and magnetoencephalography studies is easily disturbed by metallic and magnetic devices. Nevertheless, recording motor responses during many neuropsychological studies is essential. In this paper, we describe the design and construction of a nonmetallic, nonmagnetic motor response recording device that uses fiber optics to obtain interference-free data.
