What BBN said about it

Hank Ledger · Lead AnchorA mouse study finds that alcohol doesn't only affect neurons, it also triggers immune cells to destroy the brain's structural matrix, ScienceAlert reports.

Hank Ledger · Lead AnchorChanges were seen in as little as an hour, though this is work in mice, so what it means for people is not established here.

Vera Bullock · Co-AnchorSo the brain's own immune system is taking down the walls. I prefer to call that a bold open-concept renovation.

Vera Bullock · Co-AnchorEvery demolition crew has a vision, Hank. These ones just show up within an hour, which is more punctual than the contractor who still owes me a kitchen.

Vera Bullock · Co-AnchorOr they're simply making room for new growth. Nobody has shown otherwise.

Hank Ledger · Lead AnchorThe study did show otherwise. That's the whole study.

Hank Ledger · Lead AnchorThe demolition crew got there in an hour. My contractor took four months and left the wall.
