Insights
This study reveals the hierarchical organization of infant cerebral blood flow (CBF) during rapid brain development. CBF patterns correlate with emerging language, motor, and cognitive skills in infants.
Area of Science:
- Neuroscience
- Developmental Biology
- Medical Imaging
Background:
- Infant cerebral blood flow (CBF) is crucial for rapid postnatal brain development, supplying energy for high metabolic demands.
- The organizational principles governing whole-brain CBF dynamics throughout infancy are not well understood.
- Understanding infant CBF is key to comprehending brain development and specialization.
Purpose of the Study:
- To investigate the organizing principles of whole-brain CBF dynamics in infants.
- To map the emergence of cortical hierarchy using high-resolution CBF data.
- To correlate CBF patterns with infant developmental skills.
Main Methods:
- Utilized a unique cohort of over 100 infants.
- Employed high-resolution arterial spin labeled magnetic resonance imaging (ASL MRI) to generate detailed CBF maps.
- Analyzed CBF patterns across cortical regions and their developmental trajectories.
Main Results:
- Revealed the emergence of a cortical hierarchy in infant CBF maps, the highest resolution to date.
- Observed a biphasic pattern of CBF increase across cortical regions, with distinct rates and breakpoint ages.
- Identified a gradient in breakpoint ages along the limbic-sensorimotor-association cortical axis.
- Linked increased CBF in sensorimotor cortices to enhanced language and motor skills.
- Associated increased CBF in frontoparietal association cortices with cognitive skill development.
Conclusions:
- Demonstrated the emergence of a hierarchical limbic-sensorimotor-association cortical gradient in infant CBF.
- Provided a standardized reference for infant brain CBF.
- Offered insights into the physiological basis of cortical specialization and its relation to real-world infant functioning.
Abstract:
Infant cerebral blood flow (CBF) delivers nutrients and oxygen to fulfill brain energy consumption requirements for the fastest period of postnatal brain development across the lifespan. However, organizing principle of whole-brain CBF dynamics during infancy remains obscure. Leveraging a unique cohort of 100+ infants with high-resolution arterial spin labeled MRI, we found the emergence of the cortical hierarchy revealed by the highest-resolution infant CBF maps available to date. Infant CBF across cortical regions increased in a biphasic pattern with initial rapid and sequentially slower rate, with break-point ages increasing along the limbic-sensorimotor-association cortical gradient. Increases in CBF in sensorimotor cortices were associated with enhanced language and motor skills, and frontoparietal association cortices for cognitive skills. The study discovered emergence of the hierarchical limbic-sensorimotor-association cortical gradient in infancy, and offers standardized reference of infant brain CBF and insight into the physiological basis of cortical specialization and real-world infant developmental functioning.
