Neurons are not intelligent. Not at all.

They can't make decisions, they can't encode or decode complex data. They are bare stupid and if they could speak they would ask: "Who am I ? Where do I come from ? Why ?" (Same as any living thing in universe). But neurons can't ask such question. Because they are not intelligent. Remeber: they are protozoa.

* Intelligence emerges from the interaction of many neurons
* All brain models, that require any intelligence in the neurons, are wrong.
