Its entirely possible that the brain does not generate consciousness, rather it receives it (akin to radio antenna).

If you notice, all your other major sensory organs are completely passive, yet we assume that the brain is the single exception that generates senses instead of receiving them.

This is not just crazy talk, as major physicist have postulated the same thing (ie. Penrose and Hameroff’s Orch-OR Orchestrated Objective Reduction)
