Enhanced Numerical & Mathematic Abilities
Studies have shown that stimulation of the parietal cortex can enhance mathematic ability for up to 6 months following repeated stimulation sessions. Most affected was material which was learned recently.
Transcranial direct current stimulation of the posterior parietal cortex modulates arithmetic learning (Grabner RH, Rütsche B, Ruff CC, Hauser TU)
Modulating neuronal activity produces specific and long-lasting changes in numerical competence. (Cohen Kadosh R, Soskic S, Iuculano T, Kanai R, Walsh V.)
