This is a nice atlas of theories of consciousness. Relative to your own view, there will be some weird ones.
consciousnessatlas.com
Explore the ultimate map of the mind. The Consciousness Atlas is a free web app visualizing Robert Kuhn's Landscape of Consciousness—325+ theories of phenomenal consciousness in one interactive chart.

In our Trends in Cogn Sci paper we point to the connectivity crisis in task-based human EEG/MEG research: many connectivity metrics, too little replication. Time for community-wide benchmarking to build robust, generalisable measures across labs & tasks.
