An international research team develops a way to say “hello” with your mind
In a recent experiment, a person in India said “hola” and “ciao” to three other people in France. Today, the Web, smartphones, and international calling might make that not seem like an impressive feat, but it was. The greetings were not spoken, typed, or texted. The communication in question happened between the brains of a set of study subjects, marking one of the first instances of brain-to-brain communication on record.
