brain machine

Brain machines are a little-explored side-alley off the technology main-road.

It is claimed that they are the digital equivalent of acid.

The brain is supposed to have the following 'frequencies'
1. beta - you are awake,conscious, active, 'external focus'
2. alpha - dreamy state, passive , receptive
3. theta - subconscious creativity, deep relaxation
4. delta - deep unconscious, intuition & insight
5. gamma - no one knows much, but apparently connected to anxiety.
