"If you have a gut response to a story, you are not responding to something new ..you are really responding to a story you were told when you were six or seven…"

| Positronic Brain | ||
| A computer CPU with the capacity to rival a human brain. |
This is the first reference to the phrase "positronic brain", if not the first use of the word "positronic", in science fiction (see below).
| By exact count, there are seventy-five thousand, two hundred and thirty-four operations necessary for the manufacture of a single positronic brain. |

Here's another quote:
It fitted snugly into the cavity in the skull of the robot on the table...
All that had been done in the mid 20th century on "calculating machines" had been upset by Robertson and his positronic brain paths. The miles of relays and photocells had given way to the spongy globe of platinum iridium about the size of the human brain.
The word "positronic" was used by itself in Trail of the Comet, a 1936 story by James Blish:
Compare to the Laminated Mouse Brain Computer from Think Blue, Count Two (1962) by Cordwainer Smith, the neuristor from The Moon is a Harsh Mistress (1966) by Robert Heinlein, the artificial brain from The Metal Giants (1926) by Edmond Hamilton, the synthetic brain from Mad Robot (1936) by Raymond Z. Gallun and the Thorsen memory tube from The Door Into Summer (1956) by Robert Heinlein.
Thanks to Alex Mair for contributing this item.
He handled it gingerly, for it was the most complicated mechanism ever created by man. Inside the thin platinum-plated “skin” of the globe was a positronic brain, in whose delicately unstable structure were inforced [sic] calculated neuronic paths, which imbued each robot with what amounted to a pre-natal education.
(The Positronic Brain from 'Reason' by Isaac Asimov)
The Planeteer brought out a heavy hammer and applied it diligently to the slats of the crate. "Positronic - uh - secondary screen -" he replied, between mighty tugs.
