(Low Energy Neurofeedback Stimulation)
Thomas Lee Abshier, ND
*LENS (Low Energy Neurofeedback Stimulation): With LENS biofeedback the brainwaves are monitored and modified and then sent back to the brain. The total time of actual feedback is less than 20 seconds.
EEG Neurofeedback and Peripheral Biofeedback act in a way similar to giving a mirror to the brain. Conventional peripheral biofeedback sends back a signal (light, sound, vibration) that corresponds to the person's biological information (such as temperature, heart rate, muscle tension...). Conventional EEG neurofeedback sends back a perceptual representation of the brainwaves (as a spectral frequency and amplitude graph, sound, light frequency, etc.) indicating when the brain is performing in the desired manner. In both these systems, the patient must pay attention to the feedback, and know the desired outcome to reinforce and inhibit.
LENS is different from these conventional biofeedback techniques in that the perceptual and cognitive systems are bypassed. The LENS system sends information directly to the brain in it's own language using the medium of subtle electromagnetic impulses that are not seen, heard, or felt. Thus, the patient only needs to sit quietly during a treatment session so that an accurate measure of the brain's resting brain waves can be detected, amplified, modified, and fed back to the brain so as to stimulate its reaction.
The LENS neurofeedback information is sent as short pulses of extremely low energy radio waves that are related to (but not identical to) the dominant frequency of the brain at each moment. These impulses gently stimulate the brain's awareness of new possibilities with a signal intensity that is lower than the strength of ambient radio frequency signals that surround us at every moment. The key to the effect is that the timing of the pulses sent back to the brain are offset from the brain's dominant frequency by 5, 10, 15 or 20 Hz. This out of phase signal is sufficiently similar to the brain's own signals, but sufficiently different to be disturbing, and thus cause an interruption in its normal processing. The result of being presented with this dissonant signal is that the brain attempts to resolve the conflict by trying a new method of processing perceptual and abstract information.
In other words, the LENS whispers a message to the brain in its own language, a message that triggers an assessment and evaluation of its own function on a fundamental level. The LENS prompts the brain to update its method of internal communication and processing. This is somewhat like rebooting your computer to clear out programs stuck in unproductive loops.
Counseling and physical therapies that bring the body and mind into a state of proper internal and external balance have a synergistic healing effect with the LENS treatment. Counseling, energetic, homeopathic, and physical support therapies together give a reference point for the proper place of mental, emotional, and physical function. The LENS provides an opening, a possibility for the body-mind to adopt a new more effective and appropriate processing method to respond to the internal and external environment. Symptom improvement follows naturally when the brain recognizes and applies a more efficient allocation of resources and adopts this new processing strategy. Each treatment provides an incremental opportunity for the brain to adapt appropriately to life and adopt the skills that were being crowded out by the old inefficient processing methods. Over time the brain can develop a habit of using these new processing and resource allocation strategies, and eventually this new functional level can become a habitual life-ability with practice and daily nurture.
LENS therapy is especially indicated when the brain has a history of traumatic injury, whether mental, emotional, or physical. Any disease condition may be helped by adjunctive treatment with LENS, because all disease may have a pathology component associated with dysfunctional mental-emotional processing loops. The LENS treatment does not heal or reprogram the brain, it merely stimulates the brain to analyze its own function and check whether it is properly responding to the signals, circumstances and stresses of real life in the current moment, rather than responding in a chronic or reflexive way to past hurts or threats.
The change in brain function can sometimes be noticed almost immediately, or it may take a few hours to appear. The change is often reported as a welcome feeling of calm and control. But, occasionally the tiny electromagnetic LENS messages can disrupt a compensation mechanism that will cause the person may become tired, wired, or anxious for a few hours. After LENS therapy, the brain must reallocate its resources, update its processing methods, and construct a new scheme to rebalance its responses to the stresses of desire and survival.
On the procedural level, the LENS session includes a measurement of the brainwaves (dominant frequency, amplitude, and amplitude variation) at 19 different sites. From this, a map of brain activity is created which indicates the points of least and greatest processing. Then, another brain measurement is taken, and an offset graph is created which indicates which frequency, 5, 10, 15, or 20 Hz offset from the dominant frequency will provide the greatest therapeutic benefit in terms of bringing the high amplitude, high variability, points down to a lower level (which is considered to be the more functional brainwave state). After mapping, and determining offset, the therapy sessions include giving a small signal at the appropriate offset to the least active points, and working up to the most active points. Over the course of therapy, which is an average of 13 sessions (but may be more or less), the map is redone at intervals, and the treatment is continued until the therapeutic goals are achieved.
