These are my MEG/MRI compatible tactile stimulators. I designed them for Ramachandran. They poke people.. very, very well. When I add my fiber optic signaling component, the data acquisition engine will log the precise time that the subject was stimulated with speed of light accuracy. 

They look so cool! Theres 2 different types of plastic so the parts don’t stick while sliding. I’d way rather continue to design all of my research instruments from scratch than buy someone else’s parts and have to hack them together. Thanks again David Malmberg for being the best engineer to collaborate with!
