EEG, EMG, and Overt Mimicry Data from a Two‑Week Mirror‑Exposure Study Examining Facial Mimicry and Neural Mirroring in 4‑Month‑Old Infants

This dataset accompanies the paper entitled "Two weeks of mirror exposure enhances sensorimotor cortex activation but not facial mimicry in 4-month-old infants". The datasets include sensorimotor cortex activity measured by EEG, facial muscle responses measured by EMG, and observable facial movements at pre‑ and post‑test. All files share a common participant identifier, enabling merging across files.
