Abstract:
1. A system for computerized drawing and writing during functional magnetic resonance imaging (fMRI) of a user's brain by an MRI scanner located in an electromagnetically shielded enclosure for mapping the user's brain activity during a behavioral task, comprising: a) an fMRI-compatible touch-sensitive tablet having a touch-sensitive surface configured to detect user input while the user is subject to functional magnetic resonance imaging (fMRI); b) an fMRI-compatible tablet support mounted on a patient table, said touch-sensitive tablet being mounted on said tablet support, said tablet support including an adjustment means for ergonomically accessing the touch-sensitive tablet by the user; c) an fMRI-compatible visual display mechanism for displaying to the user an input made by the user on the touch-sensitive tablet; and d) a microprocessor controller connected to said visual display mechanism and said touch-sensitive tablet, said microprocessor controller being located outside the electromagnetically shielded enclosure, said microprocessor controller configured to convert the user's input to said touch-sensitive tablet into visual stimuli displayed on said visual display mechanism, log the input into temporal and two dimensional spatial coordinates, and interpret the input associated with the behavioral behavior task under fMRI investigation.
