I remember when this research was first reported some years ago.
Whilst it is not neurofeedback it is rater curious. Apparently by
stimulating parts of the brain with rotating weak electromagnetic
fields mystical experiences occur. Now it seems this technology has
been commercialized and is freely available. The fact that these
experiences can be induced raises some interesting philosophical and
ethical questions. The link below is for the website. Has anyone on
this list heard any reports arising from the use of this?
