It's not clear at all that Mouse->Human is simply a scaling problem.
It would appear that there is some emergent phenomenon (consciousness) somewhere on the scale between mouse and human. This phenomenon may be triggered by a surplus of "computational resource" with respect to "body to be controlled", which I personally think is unlikely. It may be triggered by a matching of computational resource to controllable complexity, i.e. the hands and fingers -> tool use, who knows?
There is so much we don't know about cognition. For example, are Whales/Dolphins self aware/conscious? They have the requisite brain mass, if it's simply a scaling problem.
