My basic understanding of the system:
- Electromagnetic energy (photons) at certain wavelengths will pass though brain tissue (neurons) and interact with them.
- This interaction is dependent on the neuron's polarization state (from a negative voltage (unfired), to a positive one (fired)).
- The cacophony of noise and interactions can be measured and deconvoled to show patterns.
- Groups of neurons and their polarization states can be observed (much like an fMRI scanner deconvolves magnetic impulses to show a 3D image, this system deconvoles microwave radiation from a MASER).
- The microwave carriers (which are in the GHz) operate much faster than your brain (which is KHz at best), so deconvolution and denoising techniques have plenty of data to work with.
- The radiation reflected back is in terabits per second, but your mental processes and sensory inputs are much lower, so there is a million-to-one oversampling of the data (i.e. the information is there, decoding it is key).
Obviously if I had a working system that would be my proof, but that's a widget they won't let me near! I could write volumes about this, but convincing people that it is even possible is difficult. Hopefully the graybeards and smarties out around here can piece it together. I wish I were joking, but that's up to the reader to decide. <:)
