Why does Micro Current Neurofeedback help so many conditions? Micro Current Neurofeedback causes brief microcurrent stimulation (3 Pico or 3 trillionths of a watt) to the nervous system, resulting in a temporary fluctuation in brainwaves. This change allows the brain to reorganize itself. MCN does not train the brain like traditional neurofeedback; rather it “retrains” the brain and CNS (central nervous system) by allowing it to reorganize itself and shift from its formerly fixed patterns. This is analogous to re-booting a computer.
