Fantastic Voyage II: Destination Brain

Fantastic Voyage II: Destination Brain is a 1987 science fiction novel by Isaac Asimov about a group of scientists that shrink to microscopic size in order to enter a human brain so that they can retrieve memories from a comatose colleague. Despite the title, Fantastic Voyage II: Destination Brain is not a sequel to Fantastic Voyage, which is a novelization that Asimov wrote from the 1966 film of the same name. Asimov was never quite happy with the original novel because although he was able to change some of the scientific details, it wasn't entirely his own work. Therefore, he wrote... Fantastic Voyage II as a new, separate story that shares only the central concept of miniaturized scientists entering a human body. The story takes place in the mid to late 21st century, but in a world where the Cold War has ended, yet the Soviet regime remains strong and proud. Americans and Soviets enjoy peace, but without fully accepting each other's ways, and with each always struggling for technological superiority. In this future, the Soviets have developed a miniaturization technology that can reduce a man to the dimensions of a molecule, or smaller.
