I saw something about theta waves. Surgeons for examples practice putting their brains in such a state because this makes them more effective and so on. These waves are supposed to make learning easier and also help with other things. In the documentary I saw the attached some electrode to the head of the person and then had a computer program running which helped him see wether his brain is making theta waves or not. This way he could practice making those waves.
There are also mp3s out there which use binaural beats which supposedly change your brain waves and help getting those theta waves. I think this sounds interesting but what I don't like is that most of these mp3s which use this technology are also about meditation and chakras and occult stuff like that. This makes me wonder wether using this technology is harmful. I tested an audio program which was supposed to help you fall asleep but it did nothing for me.
