1. The document discusses neuron activation signals in the brain and how they relate to EEG oscillations and blood oxygen levels. Neuron activation produces changes in blood oxygenation that can be measured by fMRI. 2. It describes how external interfaces like BCIs can record and stimulate neuron activity to restore lost functionality. BCIs can non-invasively record EEG maps or use implants to stimulate neurons. 3. It speculates that remote wireless devices could scan EEG maps using electromagnetic radiation, enabling covert abuse. Meditation changes neuron circuits and activity, strengthening neurocoherence.
