Probabilistic connectivity of the right thalamic lesion based on Magnetic Resonance Imaging (Diffusion Tensor Imaging). This analysis is overlayed on the same T1 brain image as in the Fig. 1c. Blue clusters disclose areas to which the lesion was expected to be connected (darker color indicates stronger connectivity), independently from the actual number of residual fibers. a Successive sections from the lesion bottomward show connectivity with the ipsilateral occipital region. b In more superficial sections, lesion connectivity points to a superficial linear paramedial area spanning from the ipsilateral frontal cortex through the superior parietal lobule, including also the primary somatosensory cortex (middle and most right panels). More deeply and internally, the inferior and anterior precuneus regions seem to be involved (most left panel). The inset corresponds to a mesial view further confirming the antero-posterior extension of the most superficial (frontal, parietal cortices and superior parietal lobule) and the deepest (precuneus) connections of the thalamic lesion
