Communication in organizations is equivalent to the neural network in the human body.

FORBES: Why Your Communications May Not Be Communicating

In some cases, a neural network may consider as many as a hundred variables before it makes up its mind.

"NO changes the properties of other parts of the brain's neural network at all kinds of different time scales, " he said.

BBC: Robot brains become more human

Our results suggest that a neural network of frontal lobe areas acts as a central bottleneck of information processing that severely limits our ability to multitask.

And although Yurke hasn't given up on DNA computers (he's working on a DNA neural network), he is excited about this use of DNA. Leonard Adleman is too.

FORBES: DNA May Make Computers, Not Run Them

Unlike a regular computer program, where the computer is provided with a set of instructions, a neural network behaves like human and animal brains in other words, it learns.

FORBES: Scientists Create a Schizophrenic Computer

Mountain View's secret lab stitched together 1, 000 computers totaling 16, 000 cores to form a neural network with over 1 billion connections, and sent it to YouTube looking for cats.

ENGADGET: Google simulates the human brain with 1000 machines, 16000 cores and a love of cats

The neural-network system, even at this experimental stage, works so well that Dr Mozer says that he misses it terribly when it is turned off.
