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 […]

In my work with clients, I have generally used the analogy of working at the gym. If you go once a week, you may feel better after the workout, but you are unlikely to produce any long-term changes. On the other hand, working out every day may not give a lot faster changes. I believe […]

Skull Thickness I’ve heard from a number of folks who are experts in EEG that the single factor that accounts for about 85% of overall differences in absolute EEG amplitudes is thickness of the skull.  The reality is that some people just have thick skulls.

Training Specific Bands I’m careful about trying to train down just a narrow frequency band (i.e. just delta). It’s very possible to reduce delta and increase theta or even (if there is dissociation involved) high beta. Squashes and windowed squashes are a good alternative in that they allow you to put a ceiling on a […]

When to Finish Training Usually by around 3 cycles through the blocks of training, you should be beginning to notice that changes are becoming more stable–not fading after a session. At that point I usually start stretching out the sessions. If you’ve been doing them 4 times a week, try dropping to 2; if 2 […]
