Powerful Demonstrations of How Magnets Can Affect Your Brain
April 27, 2011
Magnetic fields can improve your memory and even control your behavior and sense of morality. This video shows just how strongly they can affect your brain. New Scientist editor Roger Highfield's recitation of "Humpty Dumpty" is interrupted by magnetic interference.
Neuroscientists have also revealed that administering electricity to the scalp -- powered by a 9-volt battery -- improves video game skills. Those who received 2 milliamps of electricity to the brain played twice as well as those who received a tinier jolt.
As Popsci reported:
"It's different from transcranial magnetic stimulation, in which a magnetic coil running at high voltage is positioned close to the head. The magnets stimulate electrical responses in the brain. Transcranial direct current stimulation is just what it sounds, applying the current directly to the brain."
