How can we be certain that the consciousness is in the head-brain? For example, there are 100M neuro cells in the stomach. We also talk about making decisions based on "gut feeling". I am not saying it is any kind of proof, but hints that this saying might be based on physical experience about gut being involved in the decision making. Also, meditation traditions talk about various body parts having various kind of impact on the consciousness, stomach being one of them.

Another interesting example is the octopus. If you cut a tentacle off from the octopus, the tentacle sometimes still continues to feed the head of the octopus. So the tentacle appears to have a "brain".
