Competing systems look for the one or two frequencies that seem to be working then calibrate the feedback to only those frequencies. Beyond this time-wasting inefficiency, these systems can actually produce negative side effects by “pushing” the brain too far in a given direction.

The NeurOptimal(Neurofeedback) system is vastly different. It moves between frequencies, microsecond by microsecond, in response to what it detects your brain “saying” at that moment.
