That's debatable. There's evidence to suggest that out characteristics, consciousness and instincts aren't contained in the brain at all, but in the cerebral spinal fluid (and possibly other organs too).KenzS said:Bicentennial Man anyone?
Android's are meant to look like a human. I suppose if you gave it a human brain it would be human. The brain contains the most of our characteristics, I doubt it could be replicated.
There have been cases of people born without any brain matter, or who's brains have been reduced by fluid (hydrocephalus).
There's even a famous case of a university student with a 126 IQ and 1st class degree in mathematics, who only had 4mm of brain matter.

So I don't think simple putting a brain into an android will make it human.
I think there's more to being human than simply having a brain, and despite being 'biological machines', I don't believe that our consciousness (or soul, if you like) can be replicated easily.
Even if every part of our biological form could be recreated artificially, I think our consciousness would remain the elusive, missing piece of the puzzle.
