In the past two years there have been quite a number of fictional works dealing with the brain and its disorders.
I just found a new entry to that niche area of fiction in one of my neighborhood bookstores this afternoon: The Echo Maker by Richard Powers (FSG Press). The condition, Capgras. The dedication page, a quote by Luria.
Powers has done some remarkable fiction with the intertwine of Glenn Gould's recordings of Bach's Goldberg Variations and DNA in the massive The Gold Bug Variations and with medical science, artificial intelligence, and virtual reality in other works.
