There are two main companies that make clinical grade biofeedback systems that support both neurofeedback and peripheral feedback-- the Procomp/Flexcomp series and the C2 series, shown here. Other systems such as the Brainmaster, the A-1 EEG BF Trainer, Brainquiry Wireless systems and the WaveRider  are designed primarily for home use, for peak performance, and some, for research. The Waveriders provide some simple EMG, Heart rate and skin conductance/GSR feedback as well as EEG.

For many years, the early predecessor of the C 2  product line was our number one best-seller. We placed their systems at Harvard, Yale, many US military facilities and probably in a good 1000+ other university and private practitioner offices. The new C-2 Product line,  is a superb blend of cutting edge technology and well tested software at very affordable prices.

Prices start as low as $1989 and range to $3189 for more powerful systems with more features and channels. System include basic emg, ecg, EEG leads and SCL and temp sensors. You can add respiration sensors and an EEG kit with electrodes for nominal additional fees.

Shipping varies from 1-5 weeks from time order is placed and paid for.
