“…Some have argued that visual-spatial memory is a bilateral process, which may largely be mediated by the verbalizability of the information to be learned (van Asselen et al, 2006). To-date, pre- and post-operative ATLR studies using neuropsychological and neuroimaging techniques have produced a myriad of inconclusive data that support non-lateralized findings, including measures of navigation (Maguire et al, 1996; Jokeit et al, 2001), maze learning (Bohbot et al, 1998; Astur et al, 2002), scene recognition (Maguire and Cipolotti, 1998; Spiers et al, 2001a), plan drawing (Spiers et al, 2001b), abstract design (Piguet et al, 1994; Dige and Wik, 2001), and faces (Hermann et al, 1997; Reminger et al, 2004). Furthermore, a number of standard tests of visuospatial memory, including the Rey–Osterrieth Complex Figure, commonly used in evaluation of mTLE, do not reliably distinguish between left and right mTLE (Lee et al, 2002; McConley et al, 2008).…”
