"When a long-term memory forms, some brain cells experience a rush of electrical activity so strong that it snaps their DNA. Then, an inflammatory response kicks in, repairing this damage and helping to cement the memory, a study in mice shows."

(There are so many metaphors in this, just waiting for us to harvest them.)

Memories are made by breaking DNA — and fixing it

Nerve cells form long-term memories with the help of an inflammatory response, study in mice finds.

@catselbow I find it oddly comforting that the colored SEM image of my neurons would so directly correlate to the yarn stash my cats have taken over.

If you could look into my brain you'd see a tangle of multicolored cat hair. The air in our house is 99% fur.
@catselbow Very relatable. Our "fur"niture is likewise so composed.
