Cracking the Code of Crying Babies: How Familiarity Changes the Interpretation of Cries

Not Applicable

Completed

• Conditions: Neuronal Activity; Magnetic Resonance Imaging

• Registration Number: NCT05170178
• Lead Sponsor: Centre Hospitalier Universitaire de Saint Etienne

Brief Summary

Understanding babies' signals is essential to meet their needs. Recent works suggest that crying provides useful information, not only allowing parents to recognize their baby among others (static information), but also to distinguish between mild discomfort and pain cries (dynamic information). The perception of this information by adults involves a "parental" brain network including brain areas involved in empathy, attention, emotional regulation, motor as well as regions of the limbic system or associated with the reward network.

Detailed Description

This network is involved when listening to cries of familiar babies, or pain cries. How do we become specialist of a baby's cries? To date, no functional imaging study has examined the specific brain activations when listening to the cries of a familiar baby in different situations, particularly painful ones.
