Behind the scenes Edit

A positronic brain is a fictional technological device, originally conceived by science fiction writer Isaac Asimov (1920-1992). Its role was to serve as a central computer for a robot, and, in some unspecified way, to provide it with a form of consciousness recognisable to humans. When Asimov wrote his first robot stories in 1939 and '40, the positron was a newly discovered particle and so the buzz word positronic — coined by analogy with electronic — added a contemporary gloss of popular science to the concept.
