摘要：
The present inventionprovides a method and device torecord and visualize drawing andwriting movements during functionalmagnetic resonance imaging (fMRI)of brain activity. The system includesa touch-sensitive tablet, an elevatedmounting platform, a stylus, and acontroller box, as well as the necessarycabling and software. All equipmentresiding inside the magnet roomis non-ferromagnetic and does notinterfere with scanner operation anddoes not affect fMRI data quality.Individuals lying inside the scannerinteract with device in a natural,intuitive way, similar to writing withpen and paper. Drawing motionscaptured by the tablet are displayedthrough a pair of fMRI-compatiblegoggles or by using a projector andscreen. Other visual stimuli canbe concurrently presented with thedrawing motions for the purpose ofassessing specific aspects of humanbehavior. The system allows fora plurality of experiments to beperformed, all while brain activity ismeasured and recorded.
