If you give a preserved brain all the necessities, could it think?

I was listening to the news this morning and t was about brains in jars or something along those lines, and I started thinking, if you gave a preserved brain all the necessities (oxygen, blood, etc.), could it think? Or does it need sensory details to do that?

Edit: interesting stuff! Learned more Than I thought I would.

The sensory inputs *are* a necessity. Whether they are artificial or not, the brain is designed to process input and generate behavioral output. Without sensation to guide functioning, the bodiless person you are describing would quickly deteriorate. It could possibly be one of the most miserable existences imaginable. 

On the other hand, if you could create some matrix-style sensory input that gave rise to an intelligible reality for the person, it could be one of the most incredible existences imaginable.
