Magdalena's Brain

In Magdalena’s Brain (2006), the protagonist’s husband, Arthur, is a paralyzed Stephen Hawking–type genius. Magdalena helps him continue his work in artificial intelligence, with the new goal of developing an artificial brain “smart enough to repair [his] mind and get [him] out of this chair.” The procedure involves a “memory transfer” in which Arthur’s mind’s contents are downloaded into a bluish liquid. [...] We are not told how the fluid encodes information, but the point is that memory must appear as a physical cerebral substance.
