“…The medial parietal cortex is also implicated in higher cognitive processes such as autobiographical memory retrieval, theory of mind and self-reflection (Cavanna and Trimble 2006; Schneider et al 2014). The precuneus is also essential in visuospatial functions which are central for the integration between brain, body, and environment, as for managing internal cognitive models (Land 2014; Bruner and Iriki 2015; Peer et al 2015). Current perspectives in cognitive sciences suggest that the integration between body and environment is also crucial to coordinate spatial and chronological processes with social perception (Hills et al 2015; Maister et al 2015).…”

“…Strong selection for larger brains has been linked to the selective advantages associated with the enhanced computational abilities of a larger neocortex with more neurons (32), but it also can be linked to other neural modifications such as an increased level of developmental plasticity arising from changes in the developmental patterns associated with larger brains (28,33,34). Selection for certain aspects of brain organization, particularly in the upper parietal reorganization that is arguably associated with modern human-specific functional modifications (17), is confined primarily to the branch leading directly to H. sapiens. No other aspects of brain reorganization as described by our set of variables show evidence of fast evolution across the hominin clade.…”

“…The eigenvector of this axis shows that the dorsal arc connecting the frontal and occipital poles is the only variable loading positively on PC1, thus separating flatter from the more globular endocasts that distinguish H. sapiens (Table S4) (14)(15)(16). Although frontal changes also can influence this variable, researchers have suggested that globularization is driven by upper parietal reorganization and that this anatomical change can be associated with enhanced visuospatial integration and memory in modern humans (17). The comparatively fast evolution of the dorsal arc trait in the lineage leading to H. sapiens is consistent with such a link between brain anatomy and function, although it could be an indirect result of selection on other craniofacial hard-tissue changes (18).…”

“…Our technology is actually part of our cognitive processes, and there are several theories in current neuroscience interpreting cognition as the result of integration between brain, body, and tools [Malafouris, 2010;Iriki and Taoka, 2012;Byrge et al, 2014]. In this sense, our parietal cortex and visuospatial functions can play a major role in the management of such interactions between the nervous system, the body interface, and technological resources [Bruner and Iriki, 2016]. Interestingly, a comprehensive analysis on neural circuits in primates evidenced major human changes in the genetic expression associated with the striatum, an element of the basal ganglia deeply involved in body management [Sousa et al, 2017].…”
