Although the nervous system’s involvement in the storage and retrieval of information is not fully understood (Roudi and Latham, 2007), areas within the temporal and parietal lobes (Henson et al., 1999; Kahn et al., 2004; Wagner et al., 2005) are essential in the memory network, as activity in these areas increases during information recall (Buckner, 2004). Particularly, as the parietal lobe plays important role in visuospatial perception (Coull and Nobre, 1998; Dudkin et al., 1999), connectivity between the parietal lobes and other brain areas may be required for the storage of visuospatial information (Dudkin et al., 1999). Also, given that the geometric figures in the RCFT are complicated, successful performance on the RCFT requires organizational strategies and planning ability (Grant and Adams, 2009), which involve the prefrontal lobes (Shin et al., 2004). Thus, it could be assumed that good performance on the RCFT requires a connection between the prefrontal and parietal areas.
