The position of materialistic science is that mind is in the brain. The simplest form of this belief is that mind and consciousness are a trick or illusion of the brain and that, in fact, we are much like zombies. We are just sensory apparatus and neurons firing. A slightly more complicated view is the mind has a physical basis in the brain but manifests emergent properties that cannot be explained by the component parts. Mind is still dependent upon brain and does not exist outside it. Both approaches lead directly to the idea that we could create an artificial mind if we could assemble parts that could simulate the component parts of the brain.
I think, however, the relationship between mind and brain is more complicated. It may turn out that mind, while closely related to the brain, might operate on an informational network that spans individual brains and perhaps even different forms of life.
