I'm not saying you're wrong, but I can't see how in the world you could possibly know any of what you said. The human brain doesn't (as far as we know) seem to use backpropagation. Everything else is wide, wide open.
- corporate_shi11 7y agoI think it's accepted that neurons which interact exhibit increased axon growth between themselves. Given the local nature of biological processes I think this must therefore be the dominant process behind connection building in the brain. It's really a very general statement about neural development. I have no idea how important the high level structure of the brain is for human thought. It's possible that most brain regions are irrelevant and have more to do with regulating bodily processes than anything else, mere machinery for running a body. But who knows. The layered residual and wide reaching connections of neocortical neurons are probably equivalent to the 'airplane' in the bird flight analogy.

As normally stated it’s a positive feedback loop — if that’s all that was going on, we would be incapable of change. There are a number of non-hebbian learning paradigms (e.g., volume learning) that seem true too.
