mbrainTrain has implemented EEG motion artifact removal as for instance during walking:

But this is not an invention of mBrainTrain. There is an EEGLAB plugin for EEG motion artifact removal. We have mentioned it on www.petergamma.org. Search of it.

We saw in the www.openbci.com forum that also costumers from Arizona are interested in products from Neurospec in Stans in Switzerland such as active electrodes:

But Neurospec is very expensive. You should find these products cheaper directly from the manufacturer. Dry electrodes are for instance used in the OpenBCI Galea. And g.tec medical uses dry electrodes. We think it is worth stying the scientific literature about dry electrodes more in detail.

Some recommend also Thinkpulse electrodes:

ThinkPulse™ Active Electrode Add-on Kits

I have also searched for people who use Thinkpulse electrodes. I did not find any. Is Thinkpulse electrodes a product as the Greentek Gelfree S3 EEG cap? A product hardly any scientists use and is now sold in the www.openbci.com shop?
