Brain-behavior correlation in children depends on the neurocognitive network.

Area of Science:

• Neuroscience
• Cognitive Psychology
• Developmental Neuroscience

Background:

• Understanding brain-behavior correlations is crucial for developmental neuroscience.
• Selective attention and response inhibition are key executive functions.
• Neuroimaging studies in children provide insights into cognitive development.

Purpose of the Study:

• To investigate brain-behavior correlations in children during selective attention and response inhibition tasks.
• To determine how functional magnetic resonance imaging (fMRI) activation relates to performance in these distinct cognitive domains.
• To explore potential differences in neural activation patterns between tasks in a pediatric sample.

Main Methods:

• Functional magnetic resonance imaging (fMRI) was used to measure brain activation.
• Twelve children (aged 9.3-11.7 years) completed a visual search task (selective attention) and a no-go task (response inhibition).
• Correlations between task performance and brain activation were analyzed.

Main Results:

• Performance on the response inhibition task positively correlated with activation in the prefrontal cortex and basal ganglia.
• Performance on the selective attention task negatively correlated with activation in the superior parietal lobule and lateral premotor cortex.
• The relationship between brain activation and performance varied significantly across neurocognitive networks.

Conclusions:

• The association between neural activation and cognitive performance is complex and domain-specific.
• Different cognitive tasks recruit distinct neural networks with potentially inverse relationships between activation magnitude and performance.
• These findings highlight the intricate interplay of brain networks in cognitive function during development.
