Secondly, causal emergence, as an important concept in complex systems, also plays an important role in the research of consciousness science. A core question in consciousness research is whether consciousness is a macroscopic or a microscopic phenomenon? So far, there is no direct evidence to show the scale at which consciousness occurs. In-depth research on causal emergence, especially combined with experimental data of the brain nerve, may answer the scale at which consciousness occurs. | Secondly, causal emergence, as an important concept in complex systems, also plays an important role in the research of consciousness science.
