Dyscalculia: News from the web:

Comparatively little is known about the neurobiological correlates of mathematical learning difficulties, such as developmental dyscalculia (DD). This study presents the largest fMRI study comparing children with and without persistent DD to date. They found no group differences in brain activation using univariate, frequentist analyses. Moreover, Bayesian analyses revealed evidence for the null hypothesis of no group differences. These findings contradict previous literature and reveal the need to investigate the neural basis of DD using multivariate and network-based approaches to brain imaging.

“Calculating Faces”: Can Face Perception Paradigms Enrich Dyscalculia Research?

In this new study they propose to highlight several brain areas involved both in numerical and facial processing: intraparietal sulcus (IPS), fusiform gyrus (FFG), and hippocampus (HC). They will also consider the possibility of expanding the scope of dyscalculia research by application of face perception paradigms.
