Gasteiger published an article in Science giving their results when repeating one of Backster's effects - plant response to the killing of brine shrimp in boiling water. While these plants visibly display a clear sensory capacity, recent research has shown that other plants are able to perceive and respond to mechanical stimuli at a cellular level. Botanist Arthur Galston and physiologist Clifford L. Slayman who investigated Backster's claims wrote: There is no objective scientific evidence for the existence of such complex behaviour in plants. For some researchers, evidence of these complex communication systems -- emitting noises via gas when in distress -- signals that plants feel pain. They lack the nervous system and brain necessary for this to happen.

[9], According to biologist Patrick Geddes "In his investigations on response in general Bose had found that even ordinary plants and their different organs were sensitive— exhibiting, under mechanical or other stimuli, an electric response, indicative of excitation. A hurricane can blow a piece of straw through a palm tree: busted A hurricane can blow all the feathers off a chicken: busted Primary perception: All living things are interconnected by ESP and have emotions: busted The primary perception myth was the kooky myth of the episode and it started off on a weird note: they actually got a polygraph to react to Tory's thoughts of harming a plant.
