5Neurons soma is about 4 to 100 micrometers[13, 14] and the Axon and dendrites are about 1 micrometer thick. On the other hand computer chip components are about 45 nanometers (0.045 micrometers).[15] However to simulate one neuron would take over a dozen electrical components. Neuron signals per second are in the 1000s per second whereas transistors are in the billions per second.
