Neonatal Precursors of Neurodevelopment

Not Applicable

Recruiting

• Conditions: Premature Birth

• Registration Number: NCT04703010
• Lead Sponsor: University Hospital, Caen

Brief Summary

The NEOPRENE project proposes to examine processes that are among the earliest precursors of cognitive functions and assess 1) the relationship between neonatal cognitive precursors and cortical structure, structural connectivity and functional connectivity at birth and 2) the relationship between neonatal cognitive precursors and neurodevelopment.
