Dataset regarding: Mancini F, Wang A, Schira M, Isherwood ZJ, McAuley J, Iannetti GD, Sereno MI, Moseley L, Rae. (2019) Fine-Grained Mapping of Cortical Somatotopies in Chronic Complex Regional Pain Syndrome. Journal of Neuroscience https://www.jneurosci.org/content/early/2019/09/27/JNEUROSCI.2005-18.2019 Software requirements: - Freesurfer or csurf: http://www.cogsci.ucsd.edu/∼sereno/.tmp/dist/csurf Included in this dataset: - Table listing all participants with clinical and demographic details - Average cortical surface required to display results ("fsaverage"). Please use sphere.reg surface. - Left-hemisphere surface labels containing the map of the right hand in primary somatosensory cortex (resampled onto fsaverage/surf/lh.sphere.reg) - Right-hemisphere surface labels containing the map of the left hand in primary somatosensory cortex (resampled onto fsaverage/surf/rh.sphere.reg) - Lut colorscale to visualize the maps Please refer to the manuscript for details about the calculation of the maps. All maps are thresholded at cluster-corrected p < 0.01. The files with the map terminate with subject ID and extension .label For instance, the file name "lh-s1-sph-cpa10.label" denotates the map of the hand in the left hemisphere of participant number 10. See Table I for more details about the participant. The label should be displayed onto fsaverage/surf/lh.sphere.reg In a few cases, we could not identify any ROI with a response to fingertip stimulation (no response to either fingertip stimulation), even at uncorrected p < 0.05: subject #3, right hemisphere (patient with right CRPS); subject #20, left hemisphere (right CRPS); subject #24, left hemisphere (right CRPS); subject #28, left hemisphere (left CRPS); subject #29, right hemisphere (left CRPS). Therefore, no map is provided in these instances.
