In researching mind control a couple of years ago, I came across an older volume on autogenic training. The text was a compilation of then current international research (1961) and previous data gathered by German scientists in pre-Nazi Germany circa 1933. The ideal and target state, if I remember correctly, for autogenic training occurs between the drowsy state and the first stage of sleep. The interesting thing that stuck with me since then is that some of the original and subsequent research noted that there was a drop of at least a degree in rectal temperature (a probe was used to monitor this) that indicated that the autogenic training was being effective. Certainly, this is not my area of expertise, but it does raise some interesting possibilities for future research concerning body temperature, effectiiveness, and EMDR.
