I went to their website, and no, they do not make any mention of brain-wave measures. You're right, though; it is possible to measure other processes like heart rate.

Maybe if you go to verniers website and look. I think they have a whole sight with hardware sensors on sale, and I would imagine that the ones that can be interfaced with the mac should read ok. but don't quote me on that.
