title: Studies strive to place fMRI on firm foundation.
abstract: Research designed to reproduce and extend the scope of fMRI studies found that startling results could be produced, but that there was also a disconcerting variability among subjects. Some patients consistently showed marked changes, others showed little or no effect and a third group displayed quite variable results.
