I find this problem fascinating.

For decades we’ve puzzled at how the inner workings of the brain works, and thought we’ve learned a lot we still don’t fully understand it. So, we figure, we’ll just make an artificial brain and THEN we’ll be able to figure it out.

And here we are, finally a big step closer to an artificial brain and once again, we don’t know how it works :)

(Although to be fair we’re spending all of our efforts making the models better and better and not on learning their low level behaviors. Thankfully when we decide to study them it’ll be a wee less invasive and actually doable, in theory.)
