The Low Energy Neurofeedback System (LENS) addresses underlying neuropsychological functions by increasing the self-regulatory capabilities It appears to do this by re-toning the brain's reactions to stimulation, interrupting the inhibitory self-protective mechanisms of the brain that interfere with the connectivity, and facilitating cortical functioning that integrates subcortical electrical activity and normalizes recorded amplitudes. The emphasis is on the disrupting dysfunctional patterns and letting the brain re-establish the connections in ways it sees fit to do, without micromanagement. The mechanisms by which this process occurs are not understood at this time. If; however, the calculations generating the feedback are corrupted or removed, the improvements in functioning are not longer seen.
The average duration of treatment across all problems is approximately twenty-five sessions. Some exceptions to this average are autism, severe head injury, continuing stress disorders, and clients returning to stressful home environments. Genetics (high levels of frontal lobe alpha) increase duration of treatment. Some medications given for a specific diagnosis may have an effect on the average, as well.
