Four-Channel or More Training I’m not aware of any data comparing multi-channel with 2-channel options. In areas other than sum-channel options (synchrony, squashes, squishes, etc.) it becomes rather complicated to set up 4-channel protocols without ending up with a large number of inhibit and reward bands. One of the benefits of 4-channel over 2-channel would […]
Frequency of Training There are reasons why I would not personally train every day. One reason is that the effects of a training session may be seen anywhere from immediately during/after the session to 12-24 hours later. So even in the beginning, training every day tends to make if difficult to recognize connections between one […]
Gender-Related Differences Everything I’ve ever seen about brain function–I don’t track anatomy and geography–shows little or no gender difference. All of the work done on alpha and beta symmetry has obviously been done with men and women, and everything backs up the beta-stronger-left, alpha-stronger-right findings for emotional stability.
Handedness and Training Way back in the 90s the Othmers did a nice little study where they took a group of children and measured everything they could think measure on them prior to training, then measured again post training. It between they simply trained C3/A1 and C4/A2 per their (at that time) standard ADHD protocol. […]
Headphones You can’t use headphones with any kind of electrical circuitry, volume controls, noise-canceling ability, etc. Use plain headphones or earbuds. If you do an internet search on ear clip headphones or clip on headphones, there are many inexpensive brands that do not interfere with electrodes on the scalp the way standard headphones may.
Hemispheric Dominance If you are right-handed, as is roughly 92% of the population, your left hemisphere is dominant for language; right for music and emotional response. If you are left-handed, there is about an 85% chance that you’ll be the same as the righties. Roughly 1.2% of the population has brains that have organized to […]
Impedances The higher the impedance–the resistance to passage of the signal between the scalp and the electrode metal–the poorer your signal will be and the more likely you are to have electromagnetic fields enter artifact into the signal. High impedances are usually the result of poor connections. If you have high impedances, redo your connections. […]
Using a Gauss Meter You may pick up a Gauss meter ($36 at http://www.lessemf.com/gaussmaster.html) and see what the levels are inside where you’ll be doing your training. You’ll probably find that the field produced by the transformer on the AC adaptor for your computer are much larger than those from other sources (since the strength […]
Linking Training Sites Symmetry, synchrony/coherence and assessments should always be linked because they are training comparisons or relationships between the two channels. Comparing each channel against a separate reference allows error to creep into the measurements by adding another variable (the signal at the reference) to change the apparent relationship. The jumper/linked references allow you […]
Muscle Tension Some clients I used to run into in Atlanta would have excessive levels of muscle tension that was “invisible”. I could never find anything tense, yet they produced very high EMG levels no matter what they did. Usually training them, SMR was a good option, with whatever signal we could get, would slowly […]
