| NOTE: This State of the Art hypnosis research article addresses the current research in Top Down vs. Bottom Up processing but fails to address the the new non/pre-verbal reptillian Bottom Up research for therapists (see my Nov. 23 'Does He Really Want Help' post). The Reptillian Always WINS. There is a MAJOR revolution going on in the field of modern Hypnotherapy. Are you rolling Snake Eyes too often?

Reptilian response in a combat situation is not "fight or flight" as originally thought, but "Perceive, freeze, fight or flight" as shown by several other articles I have linked to in alt.hypnosis over the years. Even so, Ed's cited article was QUITE GOOD! I'd love to see him doing more posts like that! Lee Darrow, C.H. http://www.leedarrow.com |

| "Those Who Can't Talk SHOP Talk SHIT." -TheShadowNose NOTE: This State of the Art hypnosis research article addresses the current research in Top Down vs. Bottom Up processing of information but fails to address the the new non/pre-verbal reptillian Bottom Up research for therapists (see my Nov. 23 'Does He Really Want Help' post). The Reptillian Always WINS. There is a MAJOR revolution going on in the field of modern Hypnotherapy. Are you rolling Snake Eyes too often? If your clients are not moving, they may need some reptillian Snake Oil...
