In my lab we're using a 128 channel biosemi hardware[0] and we wish the cheaper commercial head sets could come even close to what we're using. We've played/hacked the emotiv/muse and they're both crap (from a muscle contribution to the signal perspective)… even with the signal we are getting from the 128 leads (plus 4 facial), we still feel like our hands are tied behind our backs because its not like we're measuring the neurons directly, but maybe we'll get somewhere. And then there's the headset that needs people to be a still as possible… so overall I think we're still years out for anything good that's cheaper commercially (at least something that the research will back from non muscle contribution standpoint). I'm interested in openbci, which I think will drive the prices down in the long run (along with projects like open ephys). Maybe one of these days we'll convince our PI to let us open source something to one of these projects since we're definitely relying on it (liblsl, libboost…) lol. I think something using nano-electrode arrays[1] will probably be the best for having confidence in the signal and less likely to damage the brain. I was talking to Graham Yelton over at sandia about their project to try to get a pulse on where we are: "Originally the nano-electrode array project targeted traces of dissolved lead and arsenic species in drinking water. Since then we have used modified versions of the array platform for impedance and capacitance studies of biofilm formation and vapor-phase detection, respectively. We have also applied the concept for thermo-electric nano-wires arrays, thermo-interface templates, and electrochromics (micro-pixilation). Steve’s group has deep expertise and focuses on biosensing, beyond my limited bio sensor knowledge." I would love to see that work combined with the nano mechanical systems work going on at MIT[2], a la deep brain nano neural stimulation (tdcs? meh). Who knows, maybe people are working on it now, but sometimes trying to figure out whats going on where is another problem in itself… [0] http://www.biosemi.com/ http://www.biosemi.com/ [1] http://www.sandia.gov/mstc/MsensorSensorMsystems/technical-information/nano-electrode-arrays.html http://www.sandia.gov/mstc/MsensorSensorMsystems/technical-i...
