My Dad and I were on a fly fishing trip with a guide in a long canoe-like boat on a river. When the storm came up behind us, we pulled to the side of the river and took cover under the branches of some small overhanging trees. I wasn't very concerned, as the storm wasn't all that big and I'd been in similar situations before.
When it started hailing, I became a bit more worried, but I was still reasonably relaxed. Then I saw an extremely bright flash, screamed, and ducked. My Dad and my guide never heard the scream because the thunder was instant. It took me a few seconds, but I turned around to see if they were ok. They were, and they asked me if I saw where it was. I said that I just knew that it was close. They told me that it was about 3 feet to my right, and it hit the water (my Dad said he saw a hole in the water).
I definitely felt something from it, but I can't really describe what it was. I'd pay a lot of money to be able to see a video like this of that strike.

Holy bolts, that looks like the source of the lightning is doing a distributed spatial breadth search of the potential space looking for a connection for the main jolt (the action potential event).
Could this be what the brain is doing? A group of neurons get excited (some concept or thought), and a distributed spatial search happens electrically starting at the source of excitation (literally brainstorming), until it finds the best pathway to connect to "ground" (reasoning), at which point the pathways between "source" and "ground" stay continuously excited for a measurable period of time (the ephiphany moment, learning is happening via hebbian). "Ground" is whatever that causes the source energy to drain, such as the epiphany of a solution, which makes the solution appear obvious.
About tthe first paragraph, that's exactly what it is doing.
> These electrons are zigzagging through the air as they meet paths of easier passage through the air--paths with a lower dielectric strength. Each stroke of a lightning strike is usually about 50 m (150 ft) long and lasts about 1 to 2 microseconds with a pause of about 50 microseconds before resuming another stroke in a slightly or significantly different direction.
If you have a bunch of neurons with different thresholds to trigger their action potentials, then you slowly raise the amount of activity sent to them equally, then the lowest one is going to trigger first. I guess you could call it a search.
It removes all the fine features from the funnel, most of the color and contrast information, and shrinks the resolution. It made this photo worse in every way.
To be fair, that image wouldn't exist (nor would we be having this discussion) otherwise as it wouldn't have been published to Instagram. I can't comment in regards to the photographer's filter preference though...
I bet you could do it with 5 1000fps cameras and some software trickery. The algorithm would likely be very similar to those used for superresolution merging of multiple photographs of the same scene.
The biggest problem I see is storage if you hack something together. Not just raw storage, because that is an issue, but how fast you can clear the buffer and get the image to disk.
