I recall from one of the video lectures, Dr. Nelson explaining a study where a sample of a man's blood was removed and a part of it (I don't remember which part) was put in a petri dish.  There was an experiment that followed and the sample reacted in the same way that the host did, even though they were no longer physically connected, or in the same physical location.  Does anyone else remember this example?  I would like to read the whole study.  I would appreciate a link, or name, and author of the study, so I can find it.  Thank you. 

Its in the emotion code book, by Dr Bradley Nelson. Its the in the 1st couple of chapters. You can read the book on line if you go to Youtube.
