Subject: Can brain scans tell if you are reading?

I was reading the other day and thought, "Hmm, I wonder what my brain 
activity looks like?" I knew that my visual cortex was involved as well as 
my frontal lobe (including the area for language in my left hemisphere), 
my auditory lobe must have been active too because I had music playing in 
the background.
What would a brain activity scan of a person's brain while reading look 
like?  Would it be extreamly active because of the wide array of mental 
functions being performed?  Are you creating new neural pathways at an 
accelerated rate when reading?  And does reading regularly enhance the 
brain's ability to learn(via making new neural pathways)?
