Dynamic functional connectivity associated with prospective memory success in children.

Area of Science:

• Neuroscience
• Cognitive Psychology
• Developmental Psychology

Background:

• Prospective memory (PM) involves remembering future intentions.
• Task switching, an executive function, is linked to PM success in children.
• The neural basis of PM in children remains largely unexplored.

Purpose of the Study:

• To investigate the dynamic functional connectivity underlying successful prospective memory in children.
• To identify neural mechanisms associated with PM performance in a pediatric cohort.

Main Methods:

• Analyzed resting-state functional connectivity using sliding window techniques.
• Utilized seed regions of interest (ROIs) within the PM network.
• Examined data from 108 healthy children aged 7–15 years during a PM task with a 30-min delay.

Main Results:

• Approximately 70% of children successfully recalled their intention.
• Children with successful PM exhibited greater neural connectivity dynamics between the right dorsolateral prefrontal cortex (DLPFC) and the intraparietal sulcus.
• Enhanced connectivity dynamics were also observed between the right DLPFC and the insula in successful PM participants.

Conclusions:

• Dynamic functional connectivity, particularly in the frontoparietal and insula networks, is crucial for prospective memory success in children.
• Alertness and internal-state monitoring, supported by these networks, may contribute to effective PM.
• Findings highlight the neural underpinnings of intention recall in developing brains.
