Writing and drawing are understudied with fMRI, partly for lack of a device that enables realistic approximation of this behavior, including task performance feedback and quantitative behavioural logging in the confines of the magnet. Therefore, we developed a tablet based on touchscreen technology that is accurate, reliable, and relatively inexpensive. In a preliminary fMRI experiment, we examined the neural correlates of a widely used pen-and-paper neuropsychological assessment, the Trail Making Test. The results were similar to the major results of a previous group study, which encourages us to extend the experiment and to continue developing the tablet.
