... we found that spatial information is processed in a network of brain regions symmetrically distributed on both hemispheres and that comprises dorsal frontal and parietal regions, pre‐SMA, anterior insula and, to less extent, frontal operculum, and inferior parietal lobule.
The symmetrical distribution evidenced in the omnibus meta‐analysis rules against the idea of a right hemisphere specialization for spatial cognition proposed by past studies (Fink et al., 2000; Halligan, Fink, Marshall, & Vallar, 2003; Marshall & Fink, 2001), at least if we consider the general spatial processing, regardless of the function investigated.
A bilateral dorsal frontoparietal network that includes dorsal premotor regions and frontal eye fields in frontal cortex, and precuneus, superior parietal lobule and intraparietal sulcus in parietal cortex was found commonly activated in all spatial tasks. Although to lesser extent, bilateral activations in ventral frontoparietal network were also found in the inferior frontal gyrus and in inferior parietal lobule.
This pattern of results suggests that the frontoparietal networks support a shared mechanism that is involved in the execution of all spatial functions, rather than being implicated to several task‐specific processes. The challenge is to identify such putative mechanism underlying the spatial functions.
