Bliss Meter

A new 6-channel EEG machine is now available (see below).

Looking for an affordable 2-channel EEG machine? Follow this link.

The EEG machine is situated in this box in the back. It is powered by a power bank, which is connected via the white USB cable. Data is transmitted to the PC via the black Toslink optical cable. This cable is connected to the PC via a special optical/USB adapter. The six EEG channels are O1 and O2 at the back below, P3 and P4 at the back above, and Fp1 and Fp2 in the front. The electrodes on the forehead are flat dry electrodes. The electrodes in the hairy areas are comb-like with embedded sponges for the saline electrolyte solution. The two references are on the earlobes - separate for the left and the right lobe of the brain (also flat dry electrodes).
The software for the PC has been updated to accommodate for this new 6-channel machine (see the Download section).  If you have an Intel-based MAC computer, you can run this software on your machine by installing Windows on a separate partition by using Bootcamp.  This will require no extra investment.
The gadget is very easy to be placed on the head (some care needs to be taken for the correct placement of the electrodes). The electrodes give good signals without any skin preparation, and they are comfortable to wear. All the electrodes are Ag-AgCl. The electrodes in the hairy areas are wet - they are to be used with a saline solution for the best contacts. The tension of the headband can be adjusted with a dial in the front (see the picture above). There is no wireless radiation generated by this machine, so one can comfortably meditate with it.

The following video will take you through all the steps  of using the Blissmeter EEG machine: unboxing, identifying all the parts, connecting them together, preparing the electrodes, mounting the EEG machine. And also in this video you will learn how to install the software and basic steps of how to use it.

The BlissMeter software is currently available for the Windows platform. It features raw data displays, power spectrum, coherence spectral arrays, coherence spectral maps, live correlation arrays, correlation connectivity network graph, bar graph statistics, and envelope-coherence displays.
All these charts are updated in real time during the measurements, or one can review these charts from the recordings.
