"...the elements of cyberpunk have dissolved into the whole SF genre, so itís hard to find anyone writing who doesnít owe serious debts to Gibson and his crew."
- Richard Morgan

Positronic Brain  
  A computer CPU with the capacity to rival a human brain.  

By exact count, there are seventy-five thousand, two hundred and thirty-four operations necessary for the manufacture of a single positronic brain.
From Reason, by Isaac Asimov.
Published by Astounding S-F in 1941

Here's another quote:

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.

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 and the Thorsen memory tube from The Door Into Summer (1956) by Robert Heinlein.
