Competency with numbers is essential in today's society; yet, up to 20% of
children exhibit moderate to severe mathematical learning disabilities (MLD).
Behavioural intervention can be effective, but the neurobiological mechanisms
underlying successful intervention are unknown. Here we demonstrate that eight
weeks of 1:1 cognitive tutoring not only remediates poor performance in children
with MLD, but also induces widespread changes in brain activity. Neuroplasticity
manifests as normalization of aberrant functional responses in a distributed
network of parietal, prefrontal and ventral temporal-occipital areas that support
successful numerical problem solving, and is correlated with performance gains.
Remarkably, machine learning algorithms show that brain activity patterns in
children with MLD are significantly discriminable from neurotypical peers before,
but not after, tutoring, suggesting that behavioural gains are not due to
compensatory mechanisms. Our study identifies functional brain mechanisms
underlying effective intervention in children with MLD and provides novel metrics
for assessing response to intervention.
