Early mirror-neuron brain activity as a marker for developmental delay
Mirror Neuron Network Dysfunction as an Early Biomarker of Neurodevelopmental Disorder
This study will test whether EEG and fNIRS brain responses during watching and imitating actions can help identify infants (around 9–12 months) who are at risk for social communication delays.

What this trial studies
Researchers will record EEG (mu rhythms) and fNIRS hemodynamic responses while infants, at-risk infants, and adults watch and perform simple actions to map mirror neuron network activity. The design is longitudinal for infants, with typically developing infants tested at about 9 and 12 months and at-risk infants tested at 12 months with developmental follow-up at 24 months, while adults complete a single visit for comparison. Signals will be analyzed using stochastic modeling and machine learning to find activation patterns linked to later social-communication outcomes. The project aims to define normal developmental trajectories of action observation/imitation and detect early deviations associated with later impairment.
Who should consider this trial
Good fit: Ideal participants are typically developing infants around 9 months old, infants at increased risk for social communication delay at about 12 months (for example preterm, small for gestational age, motor or language delay, or having a sibling with autism), and healthy adults aged 18–65 for comparison.
Not a fit: Children outside the narrow infant age windows, people with conditions that prevent reliable EEG/fNIRS recording (for example uncorrected sensory impairment or recent head injury), or families unable to attend on-site visits are unlikely to benefit from this protocol.
Why it matters
Potential benefit: If successful, this could enable earlier identification of infants at risk for social communication disorders so interventions can begin sooner.
How similar studies have performed: Prior EEG and fNIRS work on mirror-system activity in infants has shown promising but mixed findings, and combining both modalities with machine learning for prediction is a relatively novel approach.
