Abstract
The present invention provides a method and device to record and visualize drawing and writing movements during functional magnetic resonance imaging (fMRI) of brain activity. The system includes a touch-sensitive tablet, an elevated mounting platform, a stylus, and a controller box, as well as the necessary cabling and software. All equipment residing inside the magnet room is non-ferromagnetic and does not interfere with scanner operation and does not affect fMRI data quality. Individuals lying inside the scanner interact with device in a natural, intuitive way, similar to writing with pen and paper. Drawing motions captured by the tablet are displayed through a pair of fMRI-compatible goggles or by using a projector and screen. Other visual stimuli can be concurrently presented with the drawing motions for the purpose of assessing specific aspects of human behavior. The system allows for a plurality of experiments to be performed, all while brain activity is measured and recorded.
