Electroencephalography (EEG) is challenged by high cost, immobility of equipment and the use of inconvenient conductive gels. We compared EEG recordings obtained from three systems that are inexpensive, wireless, and/or dry (no gel), against recordings made
with a traditional, research-grade EEG system, in order to investigate the ability of these ‘non-traditional’ systems to produce recordings of comparable quality to a research-grade system. The systems compared were: Emotiv EPOC (inexpensive and wireless),
B-Alert (wireless), g.Sahara (dry) and g.HIamp (research-grade). We compared the ability of the systems to demonstrate five well-studied neural phenomena: (1) enhanced alpha activity with eyes closed versus open; (2) visual steady-state response (VSSR); (3)
mismatch negativity; (4) P300; and (5) event-related desynchronization/synchronization. All systems measured significant alpha augmentation with eye closure, and were able to measure VSSRs (although these were smaller wit</div>

phenomena equivalently to the g.HIamp. The Emotiv EPOC did not have suitably located electrodes for two of the tasks and synchronization considerations meant that data from the time-locked tasks were not assessed. The results show that inexpensive, wireless,
or dry systems may be suitable for experimental studies using EEG, depending on the research paradigm, and within the constraints imposed by their limited electrode placement and number.</span><br>

<div>Dear Tyler,
<div><br>
</div>
<div>Is there any way you could share the draft of your manuscript with me? I can promise not to share it with anyone. The reason I'm interested is because I'm thinking about using some of these systems in my research in developmental populations in countries
where access to traditional equipment is limited. </div>
<div><br>
</div>
<div>Thanks in advance - and I would, of course, understand if you suggest I wait for the accepted/published manuscript. </div>
<div><br>

<div>Best regards,</div>

<p>Hello Guruprasad,</p>
<p><br>
</p>
<p>I apologise in advance for the shameful plug of my own paper.</p>
<p><br>
</p>
<p>I have a paper currently being reviewed, where I have done a comparison between the Emotiv, B-Alert, g.Sahara and g.HIamp (using gamma cap), where the g.HIamp was our gold standard. Its called 'Measurement of neural signals from inexpensive, wireless, and
dry EEG systems' and I will hopefully be publishing it in the journal 'physiological measurement'. I compared four common neurological phenomena, the Berger effect, SSR, Mis-Match Negativity (MMN) and Event-Related Synchronisation/Desynchronisation (ERS/ERD).</p>
<p><br>
</p>
<p>I found that the B-Alert was the best system compared with our gold standard. It's signal quality is almost identical to the g.HIamp.</p>
<p><br>
</p>
<p>Hopefully that helps, keep an eye out for my paper if it gets accepted.</p>
<p><br>
</p>
<p>Kind regards,</p>

<div dir="ltr">Hi,
<div> I am Guruprasad Madhale Jadav, an engineer and a PhD student in the Techniki Fakultet, University of Rijeka, Croatia. I am working with EEGlab, Matlab and BCI 2000 to do some basic experiments with EEG and ERP in the field of signal processing.</div>
<div> I am interested to buy some entry level research grade EEG equipment for our lab within a price range of 2000 $, I have Emotiv's EEG reserach headset and I was looking for a little better equipment that would best suite our needs.</div>
<div> Any suggestion based on your personal experience and research is appreciated.</div>
