At one time we were afraid her brain was going.

The four brains certainly weren't going to mind a little dust.

God, her brain must have gone on vacation the minute she took this job.

Her brain went numb, and it was hours before she moved.

I tried to think of one, but my brain had gone blank.

That's where my brain went sour; I should have seen them.

Man, she comes around me and my brain goes south.

I didn't either, but my brain was going a mile a minute.

Thinking about her, one's own brain goes only so far.

I let myself be talked into it, then my brain went on vacation.
