These six kinds of devices were selected for their research support and professional regard. All are available to consumers and can be a great bargain for quality of life. These gadgets usually produce significant improvements in nervous system functioning. These gains are typically sustained in the long term.
Temperature biofeedback training with a thermometer
Learn to relax by increasing the blood perfusion to your fingers or toes. Trial and error learning guides you toward relaxation. Indoor/Outdoor digital thermometer with 2 second updates to 1/10th degree.
www.cliving.org/stressthermometer.htm – $19.95
Galvanic Skin Response (GSR). Skin Conductance.
Every time your autonomic nervous system changes the level of arousal or relaxation, the moisture of your skin changes. This affects the electrical conductivity of your fingers. The GSR 2, without or with accessories, cost $50 or $150. Equipment is available at the following websites:
www.mindgrowth.com/

Heart Rate Variability (HRV)
When you inhale, heart rate increases. When you exhale, heart rate decreases. Practicing smooth and strong heart rhythms in sync with breathing is good for mind and body.
www.HeartMath.com—$295 Computer program. Very popular.
www.emWave.com – $199 Handheld. Introduced July ’06. Nice.
www.StressEraser.com—handheld, $295.
www.biocomtech.com/bht.htm—$395
www.cardiologix.com
GSR & HRV combined
www.WildDivine.com—a lush computer game with 40 biofeedback challenges—sedate—$159.95.
www.SomaticVision.com Software for use with Wild Divine hardware. $80, $90.
EEG Biofeedback or Neurofeedback. Brain Wave Training.
Monitoring and interacting with your own brain waves is a powerful method. There is broad applicability to enhance sanity, health, competence, and wisdom. This device will probably improve your life in multiple ways.
The BrainMaster is a good device for consumers, but you may need professional support. Play Attention is a weaker technology but has good remote support. Pocket Neurobics is a bargain with the weakest support. Yahoo has good newsgroup support forums.
Anyone can buy EEG biofeedback units on these sites:
www.pocket-neurobics.com—stand alone, PC or wireless
www.PlayAttention.com—single channel, helmet

www.zengar.com – This is my favorite sofware. Expensive, but world class and easy to use.
There are home training systems available for use with a clinician. You may need a health care license or prescription to buy other equipment from a manufacturer or dealer.
HemoEncephaloGraphy, HEG (blood brain image with infrared sensors).
These biofeedback devices monitor blood perfusion or blood oxygenation inside the brain with an infrared sensor on a headband. When you practice at activating certain sites on the head enhance a corresponding function in the brain. HEG devices can be both hand held and computer-based.
There are two kinds of HEG: nir HEG and pIR HEG. pIR HEG uses a box shaped sensor that is worn on the forehead. It is used only for the frontal cortex, the most human part of the brain. nir HEG is a headband with flat sensors that can be positioned at different sites on the head to exercise particular brain functions. See http://www.biocompresearch.org/questionaire1.htm
For HEG and/or EEG, see www.pocket-neurobics.com
Cranial Electrical Stimulation (CES)
This device is not biofeedback. CES sends a very mild current through the brain. Strong research support, FDA approved for anxiety, depression and insomnia. Simply turn it on so low that you can’t feel it and get a better brain. Generally used for 20-60 minutes per day for a month or two. Use continuously during chemical withdrawl cravings such as when quitting smoking.
www.Healthpax.org – Best price. Approved for sale to the Government in 2006.
www.Alpha-Stim.com Best web site on the topic.

A Slight Word of Caution
Biofeedback is generally safe and fun for the whole family. I am all for healing yourself with self-training based on information from your own body. But it is possible to do biofeedback badly. Usually this happens when doing too much too soon and pushing the mind–body too hard. This is especially true when there is greater dysfunction or instability. My caution is like the common sense advice you would get about weight training—start low and increase slowly. The difference is that too much mind–body training can be less easily recognized.
When there are medical or psychiatric issues, it is prudent to work with a licensed biofeedback trainer or therapist near you. Discuss a home training unit and program to get the full benefit from devices. There is no comprehensive directory of biofeedback providers. Try finding one at:
