Zap sleeping brains for real-life Inception

摘要

If you liked the film Inception, you're going to love this. People have acquired the ability to control their dreams after a quick zap of current to their head while they slept. Lucid dreaming is an intriguing state of sleep in which a person becomes aware that they are dreaming and can control what happens. Ursula Voss at Goethe University in Frankfurt, Germany, has previously found that this heightened awareness coincides with stronger gamma brainwaves in areas called the frontal and temporal lobes. These brainwaves happen when cells fire together 40 times a second.
