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

Figure 3

Statistical parametric map for the contrast “Pinching with the affected hand” > “Imagery of the affected hand”. The figure displays the expected activation of movement-related areas, such as primary motor and somatosensory cortex, premotor cortices, inferior, and superior parietal lobule. The map was thresholded at 𝑃<0.005 uncorrected with cluster size 𝑘≥15 voxels, and overlaid onto the MNI single-subject T1 template. There were no activation for the opposite contrast “Imagery of the affected hand” > “Pinching with the affected hand” at the threshold of 𝑃<0.005 uncorrected (𝑘≥15 voxels).
