What's surprising is the desire to have a silver bullet, or not solution.

What's still amazing is fMRI can provide more visual context of what's happening in the brain, in what region, and activities that can help that improve.

There are other complementary technologies like QEEG and SPECT that can also shed a light as well.

It does seem the case that fMRI cann be more of a snapshot photo, and technologies like SPECT can provide more of a regional time lapse of activity.
