This is what I read:
"Neuroimaging of frequent internet users shows twice as much activity in the prefrontal cortex as sporadic Internet users during online tasks."
And this is how I paraphrased:
"Neuroimaging of frequent internet users shows activity in the prefrontal cortex twice as much as sporadic Internet users during online tasks."
And,
"Activity in the prefrontal cortex through neuroimaging of frequent internet users is twice as much as sporadic Internet users during online tasks."
Have I rephrased the sentence I read with the meaning unchanged? If so, which sounds easier to understand?
