SF author (and marine biologist) Peter Watts described something very much like this, only more advanced, in his book Maelstrom (2001): "Achilles Desjardins had always found smart gels a bit creepy. People thought of them as brains in boxes, but they weren't. They didn't have the parts. Forget about the neocortex or the cerebellum—these things had nothing. No hypothalamus, no pineal gland, no sheathing of mammal over…

Another great novel about emergent intelligence was Blood Music by Greg Bear. A microorganism develops swarm intelligence.

It's not needlessly provocative human neurons have shown in almost every study to be superior to all other animal neurons. Let the backlash happen and as a society let's put a stop to letting religious idiocy get in the way of science. There is an entire field of study for ethical science and I stand behind that 100%.

Only religious idiots would prefer a "normal" life over having human-brained gorilla chimeras do all the work and just consuming psychotropics all day, right?

Oh captain my captain, lead me to this promised land!

> he work is a proof of principle that neurons in a dish can learn and exhibit basic signs of intelligence

Absolutely not. This shows that you can teach neurons to exhibit a reflex behavior adapted to the given stimuli - which shouldn’t come as a surprise. At best this is jellyfish-like level of intelligence.

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? Or is it possible they spontaneously reorganize or "learn" a previously unseen behavioral pattern?

A related question: can I indefinitely test they're performing their task correctly? When operating these neurons for actual tasks, real time challenge-response-like testing is probably a good idea. But if they can learn, eventually they may be able to trick the tests. How would one design automated tests to evaluate the state of learning-capable systems?

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://arst…

Genuine question: why "should" we be going in this direction?

Is curiosity a good answer for you? For me it is.

Very few people are not brainwashed in one direction or another, there is no need to call them idiots.

It seems needlessly provocative to use human neurons to do this. Presumably they could have had the same effects with neurons from another species. It’s like they want to provoke a backlash from religious people against scientific experimentation.

Until recently I thought a neuron is a neuron is a neuron. How are they different between species?
