In paper connections among dissociation, neural and EEG complexity are presented. They implicate the EEG correlate for dissociated rnental representations of neural assemblies which actually act in the brain-mind system. As a consequence of dissociation among these rnental representations biirst EEG activity is present. Burst activity is explained as a consequence of deterrninistic chaos, which leads to emerging of the underlying order of attractors in brain physiology. This chaos is comparable to the world of possibilities and their collapse in quanturn theory. The chaos may thus serve to link quanturn events to globál brain dyriamics and rriay be connected to the quanturn superposition of brain States and the collapse.
