We are interested in the effect of practicing meditation on physiological parameters. One of these parameters are localized gamma wave activity in the left prefrontal cortex:

For this application, the more EEG channels the better. MbrainTrain offers devices with 32 and 64 channels, but has only Bluetooth transmission.
- For fast gamma waves WIFI transmission is highly desirable
2. US American Python programmer Harrison Kinsley has shown in a demonstration that we can do neurophysiological experiments with OpenBCI Python:
3. A group of Canadian researchers from the University of Calgary has shown that OpenBCI Cyton can be used instead of an Adinstruments channel recorders at a a fraction of the costs of these devices to quantify heart rate variability:

4. OpenBCI Cyton 6ch with Wifi has been validated for EEG-Based Neurophysiological Experiments by a group of researchers from South America:

5. OpenBCI Cyton 6ch with Wifi with an EEG headset is available starting from around 1 000 USD:
We do not know the costs of devices from MbrainTrain who does not publish the costs of their devices.
7. OpenBCI is on the market for around 10 years:

- We know little about mBrainTrain and who they are.
Issues of OpenBCI:
- None of the papers and the demo have a Conflict of Interest Statement which say:
*The authors declares that this site was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.
- We do not know of any major company who sell devices for scientific studies such as iWorx, g.tec medical, Biopac or Adinstruments who has picked up OpenBCI Cyton in their catalogue this this date.
- Helios and Sensors Basel are not journals of the highest level.
