<br>Sure, the Emotiv's srate is 128 Hz (Nyquist 64Hz), so you won't be getting ABRs out of that. Looking in the header there is no information about prefiltering. What the recording bandwidth really is remains obscure, but the spec says '0.2 - 45Hz, digital notch filters at 50Hz and 60Hz'. The bulk of the recorded power is in the frequency range less than 20 Hz, which is what some reports in literature are reporting as a lowpass. Some have strong views about having a recording bandwidth up to 100Hz at least when measuring long latency responses, but I'm not sure if I completely understand that perspective.<div><hr id="stopSpelling">Date: Wed, 20 Jun 2012 23:12:04 -0400<br>From: bhikshuni.lozang@insightdeliverysystems.com<br>To: eeglablist@sccn.ucsd.edu<br>Subject: Re: [Eeglablist] emotiv in eeglab<br><br>

Last time I looked the main issue with Emotiv was low resolution
(128 samples per second?), so maybe difficult to clear Nyquist
frequency. But you are supposed to be able to output the raw signal
data files if you get the developer version.<br>
<br>
It is way more expensive but I opted for Nexus-10 from MindMedia but
it only has 4 channels of EEG (but up to 2056 sps resolution) but
also has 6 channels of biodata channels. It is not wireless at the
head however (but has bluetooth to computer).<br>
<br>
Good luck!<br>
