Hm good question. I don’t know for sure.

One Problem that could however arise from this is that not only the neuron acts as a transmitter but the position of it is data in itself.

So if you reuse the neurons for multiple actions at the same time, you might be loosing information compared to a human brain due to the neuron being the same and not locally situated somewhere else.

That’s all I got though and I am not an expert. Just my thoughts as I know that we don’t understand the brain enough to even answer your question in a reliable manner
