If you died, but your brain was preserved and many years later implanted or reactivated, would it be you?

I believe consciousness will be able to be transferred in the future. Consciousness is a combination of our thoughts and feelings, an interaction of chemical and electrical processes. Computers are getting to the point where they can think in a similar way to humans, and once this is combined with a reward system then a robot will be conscious in a similar way that humans are.
