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 […]
Neurofeedback brain-training is an energy intervention. It improves the brain’s ability to produce a range of energy levels, to reduce levels of inflammation and hyper-sensitivity, to communicate efficiently within itself, etc. There are physical issues like Parkinson’s (the death of dopamine-producing neurons), Alzheimer’s (physical blocks by amyloid plaques within synapses), loss of myelin sheaths on […]
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. […]
It’s pretty common to see bruxism in folks with very low levels of SMR. They also tend to be rather rambunctious sleepers in other ways as well and may have sleep-onset insomnia. Try training SMR% (adjust to get the right frequency for the client) at Cz/A2 or at C4/A2.
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 […]
Burnout is not generally a mental issue (nor is it usually simple). The term suggests that the autonomic nervous system (ANS), which kicks into sympathetic gear in response to stress, has gone beyond its ability to respond anymore; literally the adrenals are burned out. Absolutely certainly you want to make sure that the client is […]
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 […]
Not Getting Results Asking about signs that neurofeedback is not working or is having negative effects is perfectly valid and answerable. It’s not working if the desired changes aren’t starting to happen within about 10 sessions or less. I know lots of folks (with knowledge bases 14 feet wide and 3/8 inch deep) who keep […]
Session Timing and Length When we set up designs, we don’t know if the trainer will be working in sessions that combine HEG and EEG, or doing EEG only, doing one exercise per session or three. The choice of training time is usually based on the degree of activation involved. If you are training to […]
