Lucid Dreaming Can Be Induced By Zapping Brains With Gamma Waves
By administering mild electric currents to the brain, neuroscientists from Frankfurt University have successfully induced self-awareness in sleeping volunteers. Amazingly, the technique could be used to help people take better control of their dreams. But it’s also a discovery that’s offering critical insights into the very nature of consciousness itself. Gamma waves have been linked to consciousness before — a process called gamma coherence — but this is the first time scientists have used it to coax self-awareness during the dream cycle.
