Cleve Backster - Polygraph showing Emotional Responses of Plants and Proof of Consciosness at the Cellular Level,Ā āPrimary Perception: Biocommunication with Plants, Living Foods, and Human Cellsā, 2003. Backsterās study of plants began in the 1960s, and he reported observing that a polygraph instrument attached to a plant leaf registered a change in electrical resistance when the plant was harmed or even threatened with harm.Ā In human subjects, a polygraph measures three things: pulse, respiration rate and galvanic skin response, otherwise known as perspiration. If youāre worried about being caught in a lie, your levels will spike or dip. Backster wanted to induce a similar anxiety in the plant, so he decided to set one of its leaves on fire. But before he could even get a match, the polygraph registered an intense reaction on the part of the Dracaena. To Backster, the implication was as indisputable as it was unbelievable. Not only had the plant demonstrated fear - it had also read his mind. Backster concluded that plants had some heretofore undiscovered sense (he called it āprimary perceptionā) that could detect and respond to human thoughts and emotions.
