Brain Activation in Primary Motor and Somatosensory Cortices during Motor Imagery Correlates with Motor Imagery Ability in Stroke Patients

Table 3

Significant clusters of activation for the main effects of “Pinching with the affected hand” (PA > Rest). Single-voxel uncorrected threshold 𝑃<0.005, cluster size 𝑘≥15. BA: Brodmann area at given coordinates.

^#Voxels: number of voxels in cluster. MNI: coordinates in the Montreal Neurological Institute standard brain space. 𝑇_peak: maximum 𝑇 score in cluster. The percentage of voxels from the cluster falling within the named region is indicated by the superscripted values (obtained by the SPM Anatomy Toolbox).
