It feels as if these hyper-fast educational videos are desperately trying to avoid users clicking away.
Maybe when people come to read their books - yes, books - they'll recall the little video cartoons. Maybe.
If you find the hyperactivity annoying, here's a slower video.
The above video is part of three programmes on the nervous system for AP students.
Notice the buzz of human electrical signals. The pulses.
Somewhat like the pulses in your phone signals. Just place your handset next to a speaker and you can hear them.
One of the big dangers of external EM pulses is that they interfere with the body's own signals. The dysregulation of the resting membrane potential can affect both neurons and other cells in the body. Slow and progressive degeneration of brain functions eventually become irreversible.
Wifi is also included as is the same pulsed frequency as mobile phones.
