We use a simple pneumatic device that delivers a puff of air to a finger.

Pretty low tech, but quite robust.

Hi Matt,

It depends of course on what your exact research question is, but other commonly used somatosensory stimulation techniques in combination with MEG are median nerve stimulation (see e.g. https://www.ncbi.nlm.nih.gov/pubmed/12356444 for a review), and braille stimulators (https://www.ncbi.nlm.nih.gov/pubmed/16407546), causing unproblematic artifacts in the MEG signal.

Best,
Stan

Subject: [megcommunity] somatosensory stimulation

Hello all,
I am interested in fine somatosensory stimulation techniques in MEG. What methods and tools are currently used/available (e.g. optic laser stimulation)? I have seen Tm:YAG laser stimulation mentioned multiple times in literature, however the devices available for this method are extremely limited, if not discontinued. Thanks for your time and insights!
Best,
Matt
