4-Button Square Fiber Optic Response Pad used in fMRI and MEG computer research tasks For 900 series electronic interfaces All plastic construction Physical match to OTR-1x4-SQ.


Current Designs' fMRI response pad is the perfect choice for computer response tasks used in the human brain mapping project. It is non-magnetic, non-electronic, and entirely made out of plastic, so will not add noise to the images or raise safety concerns in the MR/MEG room or similarly demanding environments. There is a less expensive, non-MR trainer available for this response pad for use outside the magnet room.
