Ah, I do suspect that my data was a little out of date. However the information I see ((URL) Word ".doc" file, or (URL) ) list the housefly at 10^5 or 100,000, to 10^6 or 1 million neurons. This is a little bigger than "400 neurons." In fact the (...) (22 years ago, 3-Dec-03, to lugnet.robotics)

(...) That was true 20 years ago. A housefly's brain contains just 400 neurons. Your PC can easily simulate a 400 neuron neural network at faster update rates than biological neurons. The problem isn't the raw computational power. ---...--- Steve (...) (22 years ago, 3-Dec-03, to lugnet.robotics)

Hello out there, maybe someone can explain to me why the current brickOS release seems to have msleep()-amnesia ;-) We've been testing the data transfer to our Lepomux device.

Hi Sebastian, (...)
