Real-time Interactive Brain Activation/Imaging: Speed of light electro-magnetic waves summed & triangulated for multi-region brain stimulation and recording.


The proposed method can be instantiated in headgear that uses hardware timed triggering (no CPU calculations) of high frequency electro-magnetic waves summed to create action-potential stimuli (and recordings). For example, a headset device could be like a more or less rigid net worn on the head. Also, electro-magnetic stimulation using "frequency pulses" coorelated with neural-activation-frequency for perceptual feature patterns and contemporary neural-net feature coorelation (AV baselines correalated to brain-measurment data) can be used to create "agent experiences" via camera, microphone, and digital data (CGI, etc.) feeds.


Here is how it would work:


Sub-neuron/region-activation level electro-magnetic waves are time-triggered to sum in specific xyz activation locations using high-frequency wave-shaping, and hardware fast signal triggering: brain regions are differentiated for stimulation and measuring. Contemporary cognitive scientists have demonstrated that specific frequencies can be correlated with specific regions, and, within a region, specific types of activity are frequency differentiated as well (eg: some acoustic features are correlated with specific frequencies).


Stimulation: The method can stimulate a simulated neural action potential (curve), at any spot, at any time in a brain-- in a number simultaneously, or sequentially, limited by information noise, hardware and cost restraints. More importantly, it can stimulate volume regions in the brain with electro-magnetic energy (with a localized amplitude variable) and facilitate neuron activation correlated with frequency patterns. With stimulation, this could create experiences that are "too loud and vivid" (as with psychedelics, or extreme pain (esp. using digital delays to multiply the stimulus signals). This method, when used with computer-brain interfacing software methods (current science) could be used for instant drug-free pain reduction, treatments for the blind and the profoundly deaf, and for passive direct-brain virtual reality with "Grand Canyon scale immersion."


Recording: sub-activation level signals that sum to create xyz action potentials become baselines for electro-magnetic receivers: the timing data can be used for real-time hardware calibration adjustments, and the baseline adjusted signals data (+ timing data) can be compared (much cross-referencing to triangulate and mitigate noise) to present 3D zoomable images of the brain in action (a low-res mobile fMRI alternative), and with computer-brain-interfacing software: prosthetic limb control (and cyborg/machine control), near-perfect lie-detectors, verified testimony, speech for the locked-in, medical monitoring devices, "dreams on TV," etc.


This should present lower costs than fMRI machines, and it has a high temporal and spatial resolution potential: smaller than cubic millimeters at GHz (30GHz = ~1 cubic centimeter limit; 60GHz = ~.5cm (wi-fi can now run at 60GHz)) -- and can be used to design portable gear with less resolution.
