"Brain freeze"?

The last brain surgery I assisted on a few weeks ago, I don't remember any
local anestheic being applied to the meninges.  The patient is given a general
anesthetic before the surgery begins and then is given a local along the line
of incision for the scalp.  I'm not sure why a local isn't necessary for the
meninges.  I think I'll ask next week...

Oh yeah, I'm not a doctor yet either. :)
