"An exocortex is a theoretical artificial external information processing system that would augment a brain's biological high-level cognitive processes. An individual's exocortex would be comprised of external memory modules, processors, IO devices and software systems that would interact with, and augment, a person's biological brain. Typically this interaction is described as being conducted through a direct brain-computer interface, making these extensions functionally part of the individual's mind. Individuals with significant exocortices would be classified as transhumans. The magazine Living Digital gave this description of the concept: "While [the traditional concept of] a cyborg has included artificial mechanical limbs embedded chips and devices, another interesting concept is the exocortex, which is a brain-computer interface. In theory, the exocortex would be a computer-like processing system that would co-exist with and enhance the power of the human brain. Neuromancer is a book that has talked about such a scenario."" - Goran Zec from Bookmarklet
