1. This document discusses neuron activation signals in the brain and how they relate to EEG measurements and blood oxygen levels. It describes how EEG maps different frequency bands to cognitive states and activities. It also discusses how external brain-computer interfaces can be used for medical applications by recording EEG signals or stimulating neurons.
2. The document speculates that remote wireless devices could potentially scan and map EEG signals without electrodes, enabling covert abuse. It suggests such devices could target brain regions to induce artificial sensations like tinnitus. However, the speculation about covert abuse technology is presented without evidence.
3. The document raises ethical concerns about potential misuse of brain mapping and stimulation technologies but presents speculative claims about covert abuse devices without clear supporting
