Moreover, the posterior superior temporal sulcus is a target for arcuate fasciculus projections where a DCDC2 allele (rs793842), which confers risk for dyslexia (Meng et al., 2005), occurs with lower temporoparietal white matter volume within a fiber distribution that appears to terminate in the posterior superior temporal sulcus (Darki et al., 2012, their Fig. 3C). Here, DCDC2 is linked to dyslexia.
