Would love to see coverage of the gentleman who, after being paralyzed for a dozen years after a bike accident, recently underwent an experimental procedure where doctors essentially connected his brain and spine with bluetooth, reimplementing his ability to walk, move, and feel across his body. While he isn’t running marathons just yet, it’s so cool to see science giving him back so much, especially after so long!

@terramater Год назад

That's absolutely fascinating! We already knew that crabs were awesome, but we didn't know to which extent. Our camera crew was in Brazil and managed to get on camera how brilliant crabs are when it comes to survival. It's super interesting to see how these crustaceans eat, scape and manage to survive in harsh conditions.

@@peggedyourdad9560 i was making a P4A joke. I'm well aware of his condition. He doesn't appear on Scishow thumbnails usually, it's just that on P4A 2 years ago someone suggested he'll pretend to be a crab and that he "has to do a good job" and since then Crank (Crab Hank) has been a thing in Nerdfighteria so i was suggesting that since he did a good job, he should be on the thumbnail instead of the crab. I'm pretty sure the crab they chose references Crank

@arjanioo Год назад

Coincidentally, I was just rereading “How many neurons does it take to change a lightbulb?”, an article posted by Kevin Mitchell on his blog. Here’s what I’ve gleaned from it: A general way to think about the evolution of neural networks is that it started with a straightforward stimulus-response mechanism and gradually developed from there. However, there is a question about whether this is accurate. According to an alternative hypothesis, neurons emerged from cells that already performed many of the functions neurons do. The real adaptation was primarily in the morphology of the cell, i.e., the axons and dendrites. According to this idea, it's not so much about a stimulus-response circuit, but rather about coordinating the movement of large groups of cells. It is not about the specific computations of individual neurons (Sherringtonian view), but rather the global dynamic patterns of large groups of neurons (Hopfieldian view).
