This article deals with the difficulties of the yet intuitive causal interpretation of the mind–body connection emphasized by metaphysical, theoretical and experimental considerations. It shows that a decisive contribution to determining the nature of this connection can be provided experimentally. This experimental test is designed within the framework of a general systems theory capable of representing the concepts of complementarity and entanglement that are involved in the description of the mind–body connection.

The quantum-like approach of psychosomatic phenomena suggests an explanation of the correlations between mind and body in terms of quantum-like entanglement, that is, without appealing to any concept of psychophysical, efficient causality. This approach is developed within the Hilbert space formalism and its general consequences are drawn. It is first illustrated by a simple, qualitative model of the placebo effect which shows that representing psychosomatic states by entangled states can explain that purely psychological factors can produce a-causal changes of physiological (...) parameters. Then, a dynamical, quantitative and predictive model of bipolar disorder which makes use of the unitarity of the temporal evolution of psychosomatic states due to biological and psychological rhythms is worked out. This model can explain some current observations, like for example the severe fluctuations in mood between depression and mania, and it can forecast the moment of shifting. In addition, it justifies the efficiency of chronotherapy on theoretical basis. (shrink)

The term complementarity plays a central role in quantum physics, not least in various approaches to defining entanglement and the conditions for its occurrence. It has, however, been used in a variety of ways by different authors, denoting different concepts and relationships. Here we describe and clarify some of them and analyze the role they play with respect to the phenomenon of entanglement. Based on these considerations we discuss the recently proposed system-theoretical generalization of the concepts entanglement and complementarity (Atmanspacher (...) et al. in Found Phys 32(3):379–406, 2002; von Lucadou et al. in J Conscious Stud 14(4):50–74, 2007; Filk and Römer in Axiomathes 21(2):211–220, 2011; Walach and Von Stillfried in Axiomathes 21(2): 185–209, 2011). We hope that a clarification regarding the specific meaning of these terms can be useful to the growing engagement with this interesting hypothesis and its critical investigation. (shrink)

The “memory of water” was a major international controversy that remains unresolved. Taken seriously or not, this hypothesis leads to logical contradictions in both cases. Indeed, if this hypothesis is held as wrong, then we have to explain how a physiological signal emerged from the background and we have to elucidate a bulk of coherent results. If this hypothesis is held as true, we must explain why these experiments were difficult to reproduce by other teams and why some blind experiments (...) were so disturbing for the expected outcomes. In this article, a third way is proposed by modeling these experiments in a quantum-like probabilistic model. It is interesting to note that this model does not need the hypothesis of the “memory of water” and, nevertheless, all the features of Benveniste’s experiments are taken into account (emergence of a signal from the background, difficulties faced by other teams in terms of reproducibility, disturbances during blind experiments, and apparent “jumps of activity” between samples). In conclusion, it is proposed that the cognitive states of the experimenter exhibited quantum-like properties during Benveniste’s experiments. (shrink)
