Neural Correlates of Simple and Complex Mental Calculation

Dysfunctional neural network of spatial working memory contributes to developmental dyscalculia

“…The role of the IPS in calculation and in spatial working memory processes has been increasingly discussed in recent years and still remains a matter of debate (Ansari & Dhital, 2006;Cohen Kadosh et al, 2005;Dehaene, Bossini, & Giraux, 1993;Dehaene, Molko, Cohen, & Wilson, 2004;Dehaene, Spelke, Pinel, Stanescu, & Tsivkin, 1999;Fias & Fischer, 2005;Knops, Nuerk, Fimm, Vohn, & Willmes, 2006;Nieder, 2004Nieder, , 2005Shuman & Kanwisher, 2004;Zago et al, 2001). A recent study in adults investigated the contributions of spatial working memory manipulation during the addition of numbers (Zago et al, 2008) .…”

The principles and practices of educational neuroscience: Comment on Bowers (2016).

“…These authors specifically considered the case of dyscalculia, which they argued is a deficit in number sense, and offered suggestions based on pedagogical theory about how this condition could be remediated. Their argument is supported by a localized abnormality in one neural area (intraparietal cortex) consistently activated during reasoning about number and set size, part of the large-scale neural network for arithmetic (e.g., (Andres, Pelgrims, Michaux, Olivier, & Pesenti, 2011;Menon, 2015;Zago et al, 2001).…”

The role of the angular gyrus in the modulation of visuospatial attention by the mental number line

“…Several neuroimaging findings indicate that the intraparietal sulcus (IPS) and the angular gyrus (ANG) in the posterior parietal cortex (PPC) are critically involved in numerical cognition (Cohen Kadosh et al, 2005;Pesenti et al, 2000;Pinel et al, 1999Pinel et al, , 2001Zago et al, 2001; for reviews, see Brannon, 2006;Dehaene, 2003;Rickard et al, 2000). Support for the role of these regions in numerical processing has also come from studies using transcranial magnetic stimulation (TMS) (Cappelletti et al, 2007;Göbel et al, 2001;Rusconi et al, 2005;Sandrini et al, 2004).…”
