Summary

This observational study looks at how the brain responds when watching others perform actions, focusing on the mirror neuron system. Researchers will measure brain activity in healthy adults and infants, including those at risk for developmental delays, using EEG and fNIRS. The goal is to understand typical development and identify early markers of neurodevelopmental disorders.
