abnormalities in major fiber bundles that connect frontal and temporal lobes, such as superior longitudinal fasciculus and uncinate fasciculus (Kubicki et al., 2002, 2003; Nestor et al., 2004; Pérez‐Iglesias et al., 2010). In schizophrenia, associations also have been reported between superior longitudinal fasciculus and working memory (Karlsgodt et al., 2008), uncinate fasciculus and verbal memory (Nestor et al., 2004; Szeszko et al., 2008), inferior longitudinal and inferior frontooccipital fasciculi and processing speed, verbal learning, and visual learning (Liu et al., 2013), diffuse white matter abnormalities and processing speed (Karbasforoushan, Duffy, Blackford, & Woodward, 2015; Rigucci et al., 2013), visual memory (Rigucci et al., 2013), and social cognition (Rigucci et al., 2013). In the current study, we found the significant association between FA values of the CC fibers connecting bilateral temporal lobe cortices and executive function scores. Studies reported association between bilateral cortical thickness reductions in the temporal lobe and executive dysfunction in schizophrenia (Hartberg et al., 2010), as well as an association between white matter volume reductions in the temporal lobe and verbal memory, attention, problem solving, and working memory dysfunctions in a follow‐up study of early‐onset schizophrenia (Andreasen et al., 2011). The current results suggest that the disconnection between
