Intuition

In my approach to the EEG, I see beta (neuron-based) activity as being conscious and more likely logical/rational/sequential. When beta stays off and the cortex receives more freely the frequency of the subconscious, intuitive thought tends to occur more frequently.

To train to “produce” intuitive thought, however, may be counter-productive. You can work an algebraic theorem most any time, but you have to leave the door open and allow intuitive flashes to arrive–and value them enough not to shove them away as “unsubstantiated.”  I would say improved intuition and creativity are often a result, but I wouldn’t make them a target of training. What keeps them from reaching the surface in a specific brain is usually excessive commitment to beta processing, and that will have plenty of other results in one’s experience.
