[Eeglablist] EEG device inquiry

[Delorme, Arnaud]

Dear Lin,

Keep in mind that the amplifier Makoto pointed at on eBay collects data with 16-bit precision while usually for research purposes it is better to acquire data with 24-bit precision. Also, inexpensive amplifiers often do not acquire data simultaneously on all channels (they have one amplifier for all data channels and acquire one channel then another etc…). This is not the end of the world but something to know and it has consequences.

Major companies in the field are (in no particular order): BIOSEMI, Brainamps, Neuroscan, Phillips Neuro, ANT, gTek etc… They offer more expensive solutions, and this is not necessarily due to the complexity of the technology, but primarily to the very low volume (only a couple of amplifiers sold per month).

Also, as important as the amplifier (if not more important) is the cap and the electrodes you use. Do not skimp on that.

Best wishes,

Arno
