A brain does not work like a computer chip

According to the BBC, a processor is the brain of a computer, but it seems that the hardware has neuroscientists baffled.

A paper published in PLOS Computational Biology wondered if more information is the same thing as more understanding. Eric Jonas of the University of California, Berkeley, and Konrad Kording of Northwestern University, in Chicago, who both have backgrounds in neuroscience and electronic engineering, reasoned that a computer was a good way to test the analytical toolkit used by modern neuroscience. However they had to admit that they were wrong.

They took an MOS Technology 6502 chip which was first produced in 1975 and famous for powering, among other things, early Atari, Apple and Commodore computers. It has 3,510 transistors and is simple enough to create simulation that can model the electrical state of every transistor, and the voltage on every one of the thousands of wires connecting those transistors to each other, as the virtual chip runs a particular program.
