Interpreting Intervention Induced Neuroplasticity with fMRI: The Case for Multimodal Imaging Strategies

Figure 1

Commonly seen fMRI activation changes. Common fMRI activation pattern changes reported in the literature include suprathreshold voxel counts (a), peak -values or sum of suprathreshold -values (b), activation location (c), peak -value location (d), and changes in laterality index (e). Some studies report changes over time, while others report differences between groups. The degrees of changes shown here are for illustrative reasons only.
