I responded with an informative post but apparently made the mistake of disclosing it was generated and it was flagged. I reviewed the post and it is correct. If you cannot see it, it says you are wrong/incomplete here and cites three studies I know of:

Beniaguev, Segev & London, "Single cortical neurons as deep artificial neural networks," Neuron, 10 August 2021, Volume 109, Issue 17, pp. 2727–2739.e3 https://doi.org/10.1016/j.neuron.2021.07.002 Open-access preprint: https://www.biorxiv.org/content/10.1101/613141v2

Randi, Sharma, Dvali & Leifer, "Neural signal propagation atlas of Caenorhabditis elegans," Nature, 623(7986), 2023, pp. 406–414 https://doi.org/10.1038/s41586-023-06683-4 Open-access preprint: https://arxiv.org/abs/2208.04790

Neurons are not individually simple, in any sense. Nor are they the only class of cell involved in cognitive processes — glial cells are involved in inhibition, memory, network modification, etc.

While I was not participating actively in the discussion - I just want to thank both participants for embodying the spirit of HN and academic discourse - especially in the face of a difficult debate that stirs strong emotions.

@svnt, @hnlmorg - this conversation - and the links it produced - are a fascinating read, and honestly gave me hope for discourse on the open internet.
