In TGD inspired theory moments of consciousness correspond to quantum jumps. The contents of consciousness is determined somehow by the comparison of initial and final quantum histories. Essential point is that entire determistic quantum histories are involved and without further assumptions it seems that timelessness characterizes conscious experience. Thus the problem is how to understand the concept of subjective time and finite duration of subjective experience. Somehow the conscious experience is not localized to infinitely short time interval but has finite duration, multilocality in time.
Second problem is to understand cognitive aspects of conscious experience.
Free will aspect is associated with any quantum jump, even that performed by electron whereas cognitive aspects and thinking probably only to very specialized quantum jumps. The concept of association sequence might provide a solution of these problems. The idea of association sequence is simply the following. There are good reasons to assume that Kahler action is not completely deterministic. One can describe the situation also in following manner.
