Raw fMRI data of controls and patients

Raw fMRI data of 14 healthy controls (HC) and 15 chronic low back pain patients (CLBP). Subject had to perform a motor imagery (MI) task during scanning session

Brain activity of the chronic Low Back Pain (LBP) group, peak activations.

<p>Cluster maxima of brain activity of the video clips of activities of daily living (“Activities”) and walking activities (“Walking”) together. All results are false discovery rate corrected (FDR, q<0.05). MNI = Montreal Neurological Institute, STG = superior temporal gyrus, MTG = middle temporal gyrus, MFG = middle frontal gyrus, OL = occipital lobe, SPL = superior parietal lobule, IPL = inferior parietal lobule, PreCG = precentral gyrus, DLPFC = dorsolateral prefrontal cortex.</p

Functional connectivity cluster maxima of the chronic Low Back Pain (LBP) group vs. healthy controls (HC), contrast walking activities (“Walking”).

<p>All results are false discovery rate corrected (FDR, q<0.05). MNI = Montreal Neurological Institute, STG = superior temporal gyrus, ITG = inferior temporal gyrus, MTG = middle temporal gyrus, MFG = middle frontal gyrus, SFG = superior frontal gyrus, SMG = supramarginal gyrus, OL = occipital lobe, SPL = superior parietal lobule, IPL = inferior parietal lobule, PreCG = precentral gyrus, PCL = paracentral lobule, SMG = supramarginal gyrus</p

An overview of the motor imagery network based on the meta-analyzes of Hétu and colleagues (2013).
