Our neurons use electricity to communicate with each other. Tangled waveforms of electrical-impulse horizontal stripes gradually change frequency up the length of the tie. From wakefulness (Beta) to Alpha, Theta, Delta, and REM sleep, this tie can almost replace your morning coffee! At the Tie Lab, we're probably some of the most severe insomniacs in the land, please send some Delta waves our way. Original illustration from an EEG test. "Real" bow tie, freestyle, self tie.
