Dear Christine and SPMers,
We have been very happy with our fiber optic response device from
Lightwave medical ([log in to unmask] or 604-875-4529). They
support a number of interface options and will build custom devices on
request. Even though it is only composed of plastic and glass, I did do
some testing to make sure there there were no artifacts in the scans. It
has been pretty robust as well, it has been stepped on and dropped
numerous times and has not failed yet. I don't have any experience with
other response devices for fMRI though.
Regards,
Kent
