Overview

• Researchers confirmed that transcranial random noise stimulation of the dlPFC improved calculation performance in participants with weaker frontoparietal connectivity.
• Stimulating the posterior parietal cortex produced no measurable gains, underscoring the dlPFC’s specific role in math task performance.
• fMRI analyses showed that stronger connectivity between the dlPFC, PPC and hippocampus correlates with greater math learning capacity.
• Teams are investigating how MRS measurements of glutamate and GABA can predict individual responsiveness to dlPFC stimulation.
• Planned follow-up studies will evaluate the longevity of stimulation benefits and strategies for integrating these protocols into education.
