As i said many times, studying many types of consciousness is an interesting occupation.
To answer your question, yes, in part we are the same consciousness which pervades every form of life, minerals, plants, animals, water, fire etc. Other aspects of consciousness are made of more subtle energies, an individual soul, as in a human being, is a unique product of countless forces at work, at times even battling with each other.
Saying that "thought " is electrical impulses produced by the brain is a gross generalization, it's more correct imho to assume that electricity, thought, consciousness are everywhere, every time.
