It's trivial (and commonplace) to get very precisely mapped
sensory-motor area signal from movement, esp. hand (e.g., finger)
movement, with fMRI.  

What do you mean by "on the net"?  If you are able to go to a
university/medical library, there are at least a hundred papers
dealing with this in any of the usual neuro-related journals.  Or are
looking for something more specific, such as a postscript image of a
brain with sensory-motor area activation for educational purposes?
