Certainly. The research on the subject is vast and growing. The reports of consciousness are always associated with brain activity. The fact that the brain is complex and the problems difficult does not mean that neurons are being pushed around by magic.
And yet no conceivable way to explain the consciousness that we all experience in the frame work of a material world has been forth coming.
We are not just talking about the evidence being found or not. We are talking about no one even being able to conceive of how it could be.
The reports of consciousness are always associated with brain activity.
I don't doubt there is a relation in the case of humans.
The fact that the brain is complex and the problems difficult does not mean that neurons are being pushed around by magic.
More to the point, the fact that the brain is complex does not mean it can magically generate consciousness.
