Abstract
What are the brain correlates of numerical disabilities? To date only few studies have examined the neuronal underpinnings of specific numerical learning disabilities like developmental dyscalculia. However, first results provide important insights if and where brains of children diagnosed with DD differ from those of typically achieving peers. Main deficits are apparent in core regions for number processing, which mainly comprise gray, as well as white matter in parietal lobes. Moreover, it already can be demonstrated that brain activation in DD is changing according to learning and intervention. The present chapter will bring together existing puzzle pieces of brain imaging findings in DD, as well as highlight some critical issues that have to be considered when comparing studies including children with DD.
