Why octopuses don’t suffer brain damage squeezing through tiny holes?

Inspired by [this post](https://www.reddit.com/r/interestingasfuck/comments/kjjz3x/octopuses_have_no_bones_and_can_squeeze_through/?utm_source=share&utm_medium=ios_app&utm_name=iossmf).

I think it’s safe to say that a human brain would not survive being squished through a pipe like that, so how does the structure between an Octopus brain and human brain (or whatever vertebrate brain is closest to them) differ, and why does that result in the ability to go through just about any hole?

Thanks in advance.
