fMRI findings
So, what does the fMRI component of the study add to our EEG findings?

We knew from EEG that people with autism seemed to be substituting arousal for early selection.

We've now confirmed that finding by showing that the brain region active with early selection shows no such activity in people with autism.

We've also shown that the compensatory late selective process, whose existence we inferred, seems to involve suppression of irrelevant stimuli rather than enhancement of relevant stimuli,
and we've shown where in the brain this process is occurring.
