Pulsed Intense-field Lasers Can Evoke EEG Contactlessly and Noninvasively, Which Might Become a Means of Manipulating Consciousness or Behaviors Remotely

Abstract

<i>Background</i>: The idea of remotely manipulating other people or animals without contact or invasion has existed long time ago. Many people have tried, but no one really make it happen. Recently, the technique of Brain-Computer interfacing is mushrooming. It was said researchers had partially realized the direct communication with brain and even the manipulation of the subject's behavior via a chip embedded in the brain. Nevertheless, for the trauma of implantation, such chip-intrusive method is not favorite to the healthy people. <i>Objective</i>: To explore a contactless and noninvasive technique to remotely manipulate the consciousness and behaviors of animals or humans. <i>Methods</i>: The anesthetized mice or sciatic nerve samples were caged in an air-filled bottle and set as the target. A pulsed intense-field laser (PIFL) beam (<i>λ</i>=532 nm; P=20 TW; <I>E</I>=0.1 J/cm2; pulse width=30 fs; <i>f</i>=1 Hz) was emitted to the targets 1.2 m away. <i>Results</i>: <i>θ-</i>Rhythm mouse brain waves were evoked and recorded, and potentials in the detached frog sciatic nerve were stimulated without contact or invasion. <i>Conclusion</i>: The experiments shown that Pulsed Intense-field Lasers can evoke EEG and potentials in nerves contactlessly and noninvasively. It inspired us that we can remotely manipulate consciousness or behaviors on animals or humans by PIFL, which might bring about development to the Information Science and provide new medical treatment.
