As described in the “What are Brainwaves?” article, the popular term “brainwaves” comes from the electrical operation of the brain, which as it operates, causes quick voltage fluctuations in the different parts of the brain.
::: FROM DEEPLY ASLEEP TO WIDE AWAKE
For convenience, brainwaves are described by their frequency, or how fast they’re waving. This is convenient because generally speaking certain frequencies correspond with certain mental states that we know.
- “Delta“ — Varies from .02 to 4 Hz (cycles per second). This is usually associated with deep sleep.
- “Theta“ — Varies from 4 Hz up to 8 Hz. This is dreaming sleep, and also when you’re daydreaming, or visualizing, or using the imagination
- “Alpha“ — 8 Hz up to 13 Hz. When you’re relaxed, but awake.
- “Beta“ — 13 Hz up to 30 Hz. Your usual waking state.
- “Gamma“ — 30 Hz up to 60 Hz.
So the simple way to look at this is: Different frequency = Different consciousness.

In a manner of speaking, it does mean ‘getting on the train!’
