Because the neural network of both hemispheres comprises the substrate of normal arithmetic skills, dyscalculia can result from dysfunction of either hemisphere, although the left parietotemporal area is of particular significance. The prevalence of developmental dyscalculia is 5 to 6% in the school-...
Both groups showed significant spatial working memory related activity in a network including occipital and parietal regions. Children with DD showed weaker neural activation compared to the control group during a spatial working memory task in the right intraparietal sulcus (IPS), the right insula ...

Results: The results revealed deficits in the alerting network-a larger alerting effect-and in the executive function networks-a larger congruity effect in developmental dyscalculia participants. The interaction between the alerting and executive function networks was also modulated by group. In addition,...

In the last 15 years, neuroimaging studies have revealed a distributed neuronal network including several cortical and subcortical areas for representing and processing numerical information. In contrast, only a few studies to date have examined the neuronal basis of DD. Existing findings suggest that ...
regarding dyscalculia from multiple disciplines addressing the subject.The acquisition of abilities in number processing and arithmetic skills is conceptualized as an experience-based neuroplastic developmental process leading to a complex, specialised neuronal network and different cognitive representations of ...
Developmental dyscalculia is a significant neural deficit with broad social impact. A number of techniques have been used to identify the brain basis of dyscalculia, and many of these have highlighted the role of the intraparietal sulci and a left fronto-parietal network in the representation of ...
Several studies demonstrated functional network alterations in DD. Yet, there are no studies, which examined the structural network integrity in DD. We compared whole鈥恇rain maps of volume based structural covariance between 19 (4 males) children with DD and 18 (4 males) typically developing ...
