neurocomputation (s) (noun), neurocomputations (pl)
An organic computer that has been built from living neurons: "One early sample or model built to test this concept or process has been constructed from leech neurons, and is capable of performing simple arithmetic operations."

"The concepts are still being researched and prototyped, but in the near future, it is expected that artificially constructed organic brains, even though they are still considerably simpler in design than animal brains, should be capable of simple pattern recognition tasks such as handwriting recognition."
