Mad scientist youtuber grows a rat brain that is learning to play Doom

Now youtuber The Thought Emporium has gone one step further in an experiment that is alternately amazing, terrifying, and leads to deep philosophical thoughts about Cacodemons. The guy's got a bunch of lab-grown rat neurons that have somehow been trained to play Doom. The experiment uses cortical rat neurons, because of their affordability and because they can learn well enough for these purposes .

The video details the process of growing the neurons, how they gradually form clusters over time and in some cases form blob-like clumps that are actually too large for the purposes of the experiment. At one point The Thought Emporium refers to these patterns of neurons and dendrites as a"galaxy" which seems entirely right, though one can't help but feel a creeping sense of unease as some of the implications of this settle in .

The Thought Emporium goes on to detail some of the ways in which the neurons are being stored and encouraged to grow, and outlines some of the techniques they intend to pursue to create, among other things, organoids from their self-organisation. They further outline how the next step is growing the neurons from skin cells rather than buying them, for cost purposes, rather than"blending a pet shop rat" .
