Understanding how to stimulate the nervous system remotely with energy is important to detect long-range neurological weapon attacks. According to Mark Hallet, chief of the Human Motor Control Section at the National Institute of Neurological Disorders and Stroke any part of the brain is a potential target for neurostimulation. Mark further states that neurostimulation causes anatomical and functional changes of brain circuits. This means the state of the brain after a neurological weapon attack may be different than before the attack. Also, prolonged exposure to neurological weapons could lead to misdiagnosis if only the brain itself is examined. Source: Non-Invasive Neuromodulation of the Central Nervous System.
When two electromagnetic fields are sent at a frequency that is too high to stimulate brain waves but differ by a frequency within the range of neural firing. neurons can be stimulated at a specific area in the brain where the two frequency meet. This area creates an envelope where the frequency is suitable to stimulate neurons.
