Apparently, all the processing goes on in something called the "hind brain" in zebra fish.
That's probably true for humans as well.
We take these simple reactions for granted, but there's often a very complex system at work.
Off topic, but I got creeped out today. I was cleaning out the garage when I spotted what looked like a glove laying on the bumper of my old 73 Grand Prix. (it needs a motor)
Anyway, I started to pick it up and it kind of stuck to the bumper a little, so I leaned in to get a closer look.
It was the desiccated body of a squirrel. The hair was all gone, with the exception of the tail, and the skin looked like raw hide. Stiff raw hide.
Of course, I immediately dropped it with a shudder. Yikes! I said.
He, or she, had draped itself on the bumper like it was trying to get cool.
I suspect that means it was feeling sick, and then died. It must have been there for several years to be so mummy like.
I came in and washed my hands with antibacterial soap. I'll get some disposable gloves before I take it out and bury it. Creepy.
I'd never seen a squirrel that looks to have died from natural causes before. It was totally intact.
