摘要: Before its discovery chaos was inevitably confused with randomness and indeterminacy. Because may systems appeared random, they were actually thought to be random. This true despite the fact that many of these seemed display intermittent almost periodic behavior before returning more ‘‘random’’ or irregular motion. Indeed this observation leads one defining features chaos: superposition a very large number unstable motions. Thus identification in biological fixed point consistent makes new therapeutic strategies possible. Recently we able exploit such points achieve control two experimental systems: cardiac tissue brain tissue.
