On the receivers' end, the process is essentially reversed by way of a computer-brain (CBI) interface. The binary code thoughts - "hola" and "ciao" - are delivered to the brain through transcranial magnetic stimulation (TMS) technology, again through the scalp. The receivers experience the messages as phosphenes, or flashes of light in their peripheral vision.
Whatever Happened To Parapsychology?
Here's where the telepathy metaphor goes a bit sideways. Receivers don't "hear" the words as internal thoughts. Rather, they decode numerical sequences in the flashing phosphenes, sort of like a mental Morse Code. Also, the binary information was not transmitted via some space-age global telecommunications matrix. It was sent by, um, email.
Still, the research team makes its case in the project's press materials: "By using advanced precision neuro-technologies including wireless EEG and robotized TMS, we were able to directly and noninvasively transmit a thought from one person to another, without them having to speak or write," writes study coauthor Alvaro Pascual-Leone of Harvard Medical School.
Can't argue with that. The study was published in the online scientific journal PLOS ONE.
