One possible way of dividing them is to find brain activity (with an
EKG or similar) which is not accompanied by muscle signals; that would
be "mental". Everything else would be "physical".

This would make a lot human activity, including REM sleep,
"physical". Unconscious brain activity would sometimes be "mental" as
well as pure "thinking". What about just thinking while pacing?

Clearly the distinction doesn't add much to our picture of what's
going on.

There are no mental objects only mental activities.
When we say we have a pain experience, a red experience,
a happy feeling, we are talking things that are happening
in our head not about physical things in our head.

So mental events are physical in the same sense that
velocity is physical or dancing is physical. It involves
a physical activity not a physical thing.

So we have to map mental events to physical events not
to physical things like neurons or brains. We have to
map them to some high level patterns of behavior of
neurons or brains.
