Only partway through the article but it was a small shock when the word 'rodent' turned up unexpectedly:
"...later, if the rodent reenters that place, the cell will fire"
Totally fair and normal of course I just had been imagining human or generic neurons/dendrites up to that point. The test species wasn't mentioned earlier as far as I can see!

It seems obvious that a humanoid robot system or other truly general-purpose AI will need a stack of model types that work in concert. An LLM could be analogous to the conscious part of our brains, while many smaller and possibly frequently updateable models might provide "muscle memory" and reflexes.
If that becomes the case, then similarly built humanoid robots might have differentiated capabilities depending on their experience, just like us.

> Today, neuroplasticity is taken as fact, but for much of the 150-year history of neuroscience, the adult brain was thought to be static
Ha, thats dismissive! the most enlightened among us still quote this static adult brain phrenology as fact because an old person in their life is slow to new concepts and who relies on an excuse themselves of being old
