I'm one of those folks who sees intelligence as the product of a bunch of neurons talking to each other via electrochemical messages. This is to distinguish myself from those who see intelligence as a product of some sort of woo, separate form the neurons and their interconnects.
Nonetheless, I realize that one can't tell the story of intelligence by discussing individual neurons. One would be hard-pressed to describe intelligence by talking about all the neurons, nor by talking about their interconnects. There's just too many of them to be able to make that jump.
But that doesn't invalidate the concept that it's all just a bunch of neurons.
