The battle over new nerve cells in adult brains intensifies

The fact that we still don't know whether or not adult brains produce new neurons is incredible to me. It feels like we know so much as a species. But at the same time we're all just wandering around in these poorly-understood meat suits.

and the question is, are we meat suits or are we driving meat suits...

For a given phenomenon that's at least logically consistent, the egg tends to end up on the faces of people who said it was impossible.

You rarely hear about the 99% of the rime when the experts where correct.

Fair point in general. However, in most cases where the debate hits the public because there are experts on both sides, I'd say it still holds.

This is experts debating other experts. One, or possibly both, sets of experts have to be wrong.

Nobody is an expert on this topic, which is why they are doing basic research. They are experts on doing brain research, and differences in how they approach things might be relevant.

You went from the experts are almost always right, to insisting there are no experts.

Their are plenty of experts for other things. But being an expert requires more than simply running an experiment.

Each experiment is more like a clue than definitive proof. So, having a mix of positive and negative results is not some major contradiction, it’s just part of gathering knowledge.

Evidence for neurogenesis is more convincing than the arguments against it.

Props to Sciencenews.org. The articles are interesting. The pages load fast. And lots of meaty references to backup the claims. Will subscribe

Can someone tell me a mechanism that would fundamentally halt the production of new neurons in adult brains? If you can't define that edge well, then it would seem very likely that new neurons do form in adult brains, given the scale of neuron to brain, even if many fewer of them do in comparison.
