Mind Interfaces

This category spans verified neuroscience (some applications) to speculative mind control. Voice-to-Skull (V2K) exploits the real Frey Effect—microwave pulses creating audible clicks via thermoelastic brain tissue expansion. The Neurophone (Flanagan) claims to transmit sound through skin stimulation. Synthetic telepathy encompasses brain-to-brain interfaces and remote neural monitoring claims. The God Helmet (Persinger) uses weak magnetic fields claimed to induce mystical experiences.

Scientific Foundation

The Frey Effect is scientifically verified; DARPA researched subvocal speech detection and transmission. Laboratory brain-to-brain communication via EEG and TMS has been demonstrated at rudimentary levels. However, remote mind-reading without contact, thought insertion via EM fields, and supernatural experiences from weak magnetic fields lack solid evidence.

Critical Assessment

This family represents spectrum from legitimate directed energy research and emerging brain-computer interfaces to unfalsifiable targeted individual testimonies and disputed God Helmet effects. The boundary between real neurotechnology and paranoid mythology remains contentious, complicated by genuine military interest in non-lethal weapons and cognitive enhancement.
