<div dir="ltr"><div class="gmail_default" style="color:#333399">Hello Jadav. Some thoughts that might be useful below. Cheers!</div><div class="gmail_default" style="color:#333399">For a good-enough research-grade system with at least 8 gel electrodes, you may have to pay at least ~$5000. Overall, you're better off sinking money into a better cleaner signal at the beginning, rather than dealing with the dirt and problems afterwards with a lot of signal processing magic. Please have a look at early chapters of Luck's ERP handbook if you have not had a chance to yet. See Cognionics and Neuroelectrics eeg systems as two examples you may want to consider. They have a low price range for sparse systems I believe. See also sparse-EEG offerings from major vendors such as Brain Products or EGI or Cortech for comparison, although they are likely out of your price range. My recommendation is to be very skeptical about any dry or "easy to put on" or "high-impedance" systems. Thus far, there is little to NO research in major journals empirically comparing various new EEG systems for quality under various conditions, and vendors tend to oversell their products without providing data to back up their claims about the interchangeability of their signals with research-grade EEG. It is likely that cheap mobile systems of great quality are still about 5 years off. It is also likely that a new generation of researchers stuck with these new EEG systems will be forced to develop new methods to deal with issues specific to these new systems, which could in the end benefit the whole eeg community (e.g., bcilab). Thanks for your attention & good luck with the process.</div><div class="gmail_default" style="color:#333399"><br></div><div class="gmail_default" style="color:#333399"><br></div><div class="gmail_default" style="color:#333399"><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Mar 9, 2015 at 5:58 AM, Guruprasad Madhale Jadav <span dir="ltr"><<a href="mailto:guruprasadjadav@hotmail.com" target="_blank">guruprasadjadav@hotmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
