I think the interesting (and scientifically unanswered) question here is: what is the minimum amount of a neuron needed for information processing alone?

If we look at the other side, the replication (giant fab facilities) and energy production/management (power lines, PSUs, etc) are separate from the information processing in a computer chip. But, if we consider all of the pieces involved in power generation and replication as part of the chip (just like a brain has), then the complexity of the brain seems loosely equal.
