Form and | function are intimately tied in the brain and just a bunch of | neurons on a petri dish isn't quite an organ. | Kalanos wrote: | 10 points to gryffindor | seydor wrote: | i would urge people to read the paper instead. The 'learning' is | a bit iffy , and this was meant to test the brain theory of | Friston rather than plug neurons into pong. Still, great job on | the neurotechnology involved and a step in the direction where we | should be going, controlling large numbers of neurons | | Ars Technica has a better article, although they dont describe | the dense electode array correctly: | https://arstechnica.com/science/2022/10/a-dish-of-neurons-ma... | sidewndr46 wrote: | A question for someone who understands the neurology and biology | of this much more than I do: | | Once I have a group of neurons like this trained to do something, | can I actually count on them to continue performing that task | until they die?
