It certainly doesn't put a halt to brain activity. You might not be aware of anything that's going on while you're under, or remember anything afterwards (although some people do,) but that doesn't mean that your brain isn't doing anything. If you put someone under general anesthetic under an electroencephalogram, you'd register plenty of activity.
Ah yes, didn't think of that. Even while I'm concious my brain is doing things I'm/it's not aware of.
