these are patterns of a simulation, not actual brain activity https://en.wikipedia.org/wiki/Blue_Brain_Project https://en.wikipedia.org/wiki/Blue_Brain_Project

  The simulation is based on a pretty detailed mapping of how actual rat brains are connected so it should be fairly accurate.

    But how should one validate that it actually does something sensible?

      One of the simplest known organisms, the worm C. Elegans, has a brain consisting of 302 neurons that we have mapped exactly. (The entire thing is 959 cells.) We still can't simulate it correctly. A rat's brain is O(10^7) neurons, while a human brain is O(10^11) neurons, as compared to C. Elegans with O(10^2) neurons. Which is to say, trying to simulate a rat brain while we know we can't simulate C. Elegans is like a prehistoric human claiming he can build an F1 racecar before he's invented the wheel.
