No Evidence for Systematic White Matter Correlates of Dyslexia and Dyscalculia

Dyscalculia: News from the web:

A very interesting study has been completed. They compared people with dyslexia, dyscalculia, both and neither. They focused on the corona radiata and the arcuate fasciculus, two tracts associated with reading and mathematics in a number of previous studies. Using Bayesian hypothesis testing, they showed that the data showed no differences between groups for these particular tracts, a finding that seems to go against the current view in other studies.
This outcome, if confirmed, suggest that structural differences associated with dyslexia and dyscalculia might not be as reliable as previously thought, and this may have some impact on how we approach remediation.

How do you process magnitudes?

Dyscalculia: News from the web:

Interesting study which outcome favors the possibility of a generalized magnitude system in the occipito-parietal lobe. It might be further assumed, that with development more refined and specific neuronal functions form in order to process magnitudes with increasing difficulty (Leibovich and Henik, 2013). Secondly, despite the numerical deficits and difficulties in more complex spatial skills, adolescents with DD seem to have well developed abilities to process discrete and continuous magnitudes. Neuronal findings may reveal the use of compensatory systems, hinting to a slight delay in the development of the discrete and continuous numerical system. Further studies are needed to examine the development of the generalized magnitude system in typical and, more importantly, in atypical development.
