Computer-aided telepathy is beginning to become a real thing, potentially enabling communication between people by transmitting their thoughts through devices connected to their brains. Bioengineer and neuroscientist Bradley Greger, a Fulton Schools associate professor of biomedical and health systems engineering, says questions still need to be answered about how much information can actually be gathered from the brain using such devices. But some experts are already speculating that the new telepathic technologies might someday give rise to brain-to-brain communication services.
