Figure 4.

Variability of brain activation to speech as compared with signal-correlated-noise, SCN. Significant activation to speech vs. SCN after small volume correction is displayed in the left and right hemisphere of three patients. Red voxels indicate activation before and blue ones after the therapy interval. Pink voxels show significant activation before and after therapy. Statistical analyses failed to reveal any significant change of activation in the speech vs. SCN contrast over therapy in any of the patients. Note the variability of speech-related activation over patients.
