A common theme of science fiction in the transhumanist vein, and less commonly in applied (read: practical) transhumanist circles is the concept of having an exocortex either installed within oneself, or interfaced in some way with one's brain to augment one's intelligence. To paint a picture with a fairly broad brush, an exocortex was a system postulated by JCR Licklider in the research paper Man-Computer Symbiosis which would implement a new lobe of the human brain which was situated outside of the organism (though some components of it might be internal). An exocortex would be a symbiotic device that would provide additional cognitive capacity or new capabilities that the organism previously did not posses, such as:
- Identifying and executing cognitively intensive tasks (such as searching for and mining data for a project) on behalf of the organic brain, in effect freeing up CPU time for the wetware.
- Adding additional density to existing neuronal networks to more rapidly and efficiently process information. Thinking harder as well as faster.
- Providing databases of experiential knowledge (synthetic memories) for the being to "remember" and act upon. Skillsofts, basically.
- Adding additional "execution threads" to one's thinking processes. Cognitive multitasking.
- Modifying the parameters of one's consciousness, for example, modulating emotions to suppress anxiety and/or stimulate interest, stimulating a hyperfocus state to enhance concentration, or artificially inducing zen states of consciousness.
- Expanding short-term memory beyond baseline parameters. For example, mechanisms that translate short-term memory into long-term memory significantly more efficiently.
- Adding I/O interfaces to the organic brain to facilitate connection to external networks, processing devices, and other tools.
