Figure 2.

Causal chains in the world, body, and brain affect the reentrant dynamic core. Core activities (C′) in turn affect further neural events and actions. Core processes confer the ability to make high-order distinctions. The entailed qualia (C) consist of those distinctions. The shaded area labeled “phenomenal transform” has no causal efficacy but consistently reflects the C′ states, which are causal. The boundary of the dynamic core in the figure should not be interpreted too strictly, because in real brains it fluctuates in time.
