Sure, Kate. Neurons are more complex than a simple transistor. Balance this, with the speed of information propagation through the brain. The top speed of inter-neuron information exchange is 3 million times slower than electrical signals in a copper wire.

There are a hundred thousand transistors in an average PC for ever neuron in an Earthworm's brain. The propagation of information between these transistors is vastly faster than that for the Earthworm's brain. An Earthworm's behavior isn't significantly modified by having it's brain removed.

Do you still think Rob's "point" that an Earthworm has more processing power than a PC, is true?
