In vitro neurons learn and exhibit sentience when embodied in a simulated game-world
Neuron ^ | October 12 2022 | Brett J. Kagan

Integrating neurons into digital systems may enable performance infeasible with silicon alone. Here, we develop DishBrain, a system that harnesses the inherent adaptive computation of neurons in a structured environment. In vitro neural networks from human or rodent origins are integrated with in silico computing via a high-density multielectrode array. Through electrophysiological stimulation and recording, cultures are embedded in a simulated game-world, mimicking the arcade game “Pong.” Applying implications from the theory of active inference via the free energy principle, we find apparent learning within five minutes of real-time gameplay not observed in control conditions. Further experiments demonstrate the importance of closed-loop structured feedback in eliciting learning over time. Cultures display the ability to self-organize activity in a goal-directed manner in response to sparse sensory information about the consequences of their actions, which we term synthetic biological intelligence. Future applications may provide further insights into the cellular correlates of intelligence.

It would seem that they are trying to create an AI that displays the psychological characteristics of a sociopath.

I will do what ever I want whatever the consequences.

How did they get these human neurons?

Well, at least fetuses aren’t sentient before their hearts start beating.

It appears to be : “embryonic rodent and human-induced pluripotent stem cells” According to the article.

Kind of proves the pro-life argument, me thinks.

Time to plug William Gibson's 1984 science fiction novel 'Neuromancer' yet again.
(Yes, it was published in 1984. LOL...)

:D
I’d gone down the Star Trek voyager route, with bioneural computing.
