“…The reported study results corroborate the first assumption because complex arithmetic operations thought to be solved using quantity manipulations were modulated by IPS TMS ( Andres et al, 2011 ; Salillas et al, 2012 ; Montefinese et al, 2017 ; Fresnoza et al, 2020 ), tDCS ( Hauser et al, 2013 ; Kasahara et al, 2013 ; Klein et al, 2013a , b ; Houser et al, 2014 , 2015 ; Artemenko et al, 2015 ) and high-frequency tRNS stimulation ( Pasqualotto, 2016 ; Popescu et al, 2016 ). TMS studies also hinted at the right IPS dominance for online calculation ( Salillas et al, 2012 ; Montefinese et al, 2017 ; Fresnoza et al, 2020 ), which might be explained by a disruption of not only the right-lateralized ventral spatial attention system in charge of automatic orienting but also the right component of the bilateral spatial attention system in charge of intentional orienting ( Corbetta and Shulman, 2002 ; Wassermann et al, 2008 ; Chica et al, 2011 ).…”

This systematic review presented a comprehensive survey of studies that applied transcranial magnetic stimulation and transcranial electrical stimulation to parietal and nonparietal areas to examine the neural basis of symbolic arithmetic processing. All findings were compiled with regard to the three assumptions of the triple-code model (TCM) of number processing. Thirty-seven eligible manuscripts were identified for review (33 with healthy participants and 4 with patients). Their results are broadly consistent with the first assumption of the TCM that intraparietal sulcus both hold a magnitude code and engage in operations requiring numerical manipulations such as subtraction. However, largely heterogeneous results conflicted with the second assumption of the TCM that the left angular gyrus subserves arithmetic fact retrieval, such as the retrieval of rote-learned multiplication results. Support is also limited for the third assumption of the TCM, namely, that the posterior superior parietal lobule engages in spatial operations on the mental number line. Furthermore, results from the stimulation of brain areas outside of those postulated by the TCM show that the bilateral supramarginal gyrus is involved in online calculation and retrieval, the left temporal cortex in retrieval, and the bilateral dorsolateral prefrontal cortex and cerebellum in online calculation of cognitively demanding arithmetic problems. The overall results indicate that multiple cortical areas subserve arithmetic skills.

“…Interestingly, for novel and complex subtractions, left parietal tDCS prevented characteristic prefrontal deactivations below the right prefrontal cathode as captured with simultaneous fMRI (Hauser et al 2016) and this configuration improved reaction times (Hauser et al 2013). In another paradigm, after viewing an instructional video, administering a complex statistical procedure was enhanced from left parietal anodal tDCS with a temporal cathode (Houser et al 2015), but not with placement of a prefrontal cathode (Houser et al 2014). Also considering neurodevelopmental studies, the accumulation of arithmetic proficiency may be accompanied by a shift from broad prefrontal to precise parietal activations (Zamarian et al 2009).…”

Arithmetic capabilities are complex cognitive skills essential for handling requirements of the modern world. At the same time, educational institutions are challenged with mathrelated problems, e.g., developmental dyscalculia and math anxiety, and also with less severe difficulties of arithmetic understanding. Thus, non-invasive techniques for cognitive enhancement have attracted researchers' and practitioners' interest in the fields of education, psychology, and neuroscience. Particularly, studies employing transcranial electric stimulation (tES) in arithmetic learning, problem solving, and performance in numerical tasks and operations have shaped an optimistic perspective of cognitive enhancement in these domains, building on the fronto-parietal correlates of healthy and deficient arithmetic performance and learning. However, the heterogeneity of stimulation approaches in numerical cognition researchwith different electrode montages, stimulation protocols, tasks, outcomes, and combinations thereof-may also showcase a variety of parameters relevant more generally to the cognitive domain. Here, we present a short overview of the different tES approaches to enhance numerical and arithmetic capabilities in performance and training within the general framework of cognitive enhancement. We conclude that performance and training gains can be obtained from different strategical tES configurations, but more standardization, better translation between neurodevelopmental perspectives and tES principles, as well as pre-registered and controlled studies in critical populations are needed.

“…Channel 5 is located in the left inferior frontal gyrus (IFG) and channel 31 is located in the left intraparietal sulcus (IPS). The involvement of the left IFG in arithmetic has been discussed in Case 1 and the activation of the left IPS in arithmetic has been reported in studies of Bugden et al (2012) and Houser et al (2015).…”

“…Specifically, the inferior prefrontal gyrus is activated in working memory processing while the fusiform gyrus is activated in number form decoding and building visuo-spatial representation of numerical quantity (Fias et al, 2013;Menon et al, 2020). In the study conducted by Zhao of Bugden et al (2012) and Houser et al (2015).…”

Developmental dyscalculia (DD) is a heterogenous mathematics learning difficulty, affecting approximately 4 to 7% of children. Despite its prevalence, our current understanding of the neural underpinnings of DD remains limited. This study probed DD’s neural heterogeneity through case study comparative analyses between dyscalculia-at-risk children (DR) with non-dyscalculia-at-risk (NDR) children. Utilizing functional near-infrared spectroscopy, brain data from resting states and a mathematical computation task (addition) were acquired and analysed, using Graph theory assessing brain global and nodal network indicators. By comparing DR cases’ network indicators and activation with NDR children’s data, three DR cases demonstrated lower nodal efficiency, providing insights into potential early biomarkers of DD. Moreover, the thorough investigation of single cases can offer valuable insights for devising personalized interventions for children with DD.Research HighlightsAlthough the behavioural and cognitive heterogeneity of developmental dyscalculia (DD) has been investigated, its neural heterogeneity is under-researched.Case-control design empowers researchers to probe individual idiosyncrasies, transcending the constraints imposed by summary statistics derived from group comparisons.Graph theory metrics provided insights into the topological organization of the brain areas that underpins mathematical tasks, extending researchers’ understandings of their brain activations.Three dyscalculia-at-risk cases not only demonstrated different behaviorual and neural profiles, but also showed similar neural deficits, providing insights into potential early biomarkers of DD.
