Consciousness as causal input

Instead of being only an output (what the brain produces), consciousness may act back on the brain as an actual input that alters neural processing and behaviour. This reverses the usual one‑way model and suggests measurable feedback effects between subjective experience and neural states. — If true, the idea reshapes debates about free will, criminal responsibility, mental‑health treatment, and how we evaluate claims of consciousness in AI or nonhuman animals.
