Ear stimulation may boost letter learning in dyslexic teens

This study tests whether a mild, non-invasive stimulation of the vagus nerve (through the ear) can help teenagers with dyslexia learn new letter-sound connections. About 100 adolescents with either typical reading skills or dyslexia will take part. They will complete six 30-minute training sessions while receiving either real or fake stimulation, and undergo brain scans to see how their brains respond. The main goals are to see if the approach is safe and tolerable, and whether it improves learning and brain plasticity.
