In honor of @Foone's thread on the *visual* quirks of our brains, let's talk about "how bullshit insane our brains are": sensory and motor systems edition.https://twitter.com/Foone/status/1014267515696922624 …

Just like with the visual system, "hack your time perception" is trick is one that our brains employ a whole lot, to try make actions *appear* as if they're happening at the same time. This probably makes cause-and-effect easier to associate.

For example, try scratching your leg. You can feel your hand move; you can feel force in your fingers. You can feel your nail on your skin. Feels like they're all happening at about the same time, right? Wrong.

Your motor commands zips down from your brain through α-motor neurons to your fingers at around 100 m/s. They move; your legs then feel that scratch slowly at 40 m/s through type II sensory fibers. That signal's roundtrip takes 40-50 ms to just travel through your body.

After the sensory signals process, 100-200 ms has passed - from intent to conscious sensation. For reference, that would be the network roundtrip time from the US west coast, all the way to Europe, *and back*.

Crazy thing is, if that happened in a game you're playing, you would complain about lag. But for scratching, you *don't feel it at all* - your brain hacked time perception backwards to make you think the movement intent, the movement, and the sensation occurred at the same time.

My favourite example - give someone a task with a standard computer mouse, but slowly add latency to the screen cursor. Do it slow enough and you can add seconds of latency and they won't notice. But suddenly remove that latency and they think the cursor is "reading their mind"!
