FIGURE 7.

Cortical areas potentially involved in proprioceptive and cross-reference processing. M1, S1: primary motor and somatosensory area, respectively. STG: superior temporal gyrus. Posterior parietal cortex (PPC), including the supramarginal gyrus (SMG), the superior parietal lobule (SPL), and the intraparietal sulcus (IPS). Areas in blue: cortical areas preferentially involved in W-A_P, purely proprioceptive tasks (Butler et al., 2004; Iandolo et al., 2018; Marini et al., 2019). Green: enhanced activity when the task requires cross-reference processing in symmetric between-arms tasks (sB-A_P) as in Ben-Shabat et al. (2015) and Iandolo et al. (2018); red: in the symmetric between-arms tasks (sB-A_VP) as in Semrau et al. (2018); purple: in the asymmetric between-arms task (aB-A_P) as in Pellijeff et al. (2006); yellow: in cross-modal (C-M_P) tasks as in Grefkes et al. (2002), Butler et al. (2004), and Van de Winckel et al. (2012).
