Seeking the title of a science fiction novel

Someone had left the brain of a doctor (who seemed to be a physics doctor) and placed it in a nutrient solution to survive. There was a computer or some machine to help it speak. The doctor couldn't move and could only wait for someone else to come.
Uh, I forgot about the rest. Please help me list them. Thank you!
