Brain activation during cognitive control tasks differs substantially between people but is reliable within...

Area of Science:

• Neuroscience
• Cognitive Neuroscience
• Neuroimaging

Background:

• Understanding the neural basis of cognitive control is crucial but remains incomplete.
• Previous neuroimaging studies often use group averages and limited tasks, obscuring individual brain organization.
• Precision neuroimaging offers potential but typically uses limited tasks or resting-state data.

Purpose of the Study:

• To introduce and validate a dense neuroimaging approach combining precision methods with an extensive task battery.
• To investigate the reliability and specificity of neural activity patterns related to cognitive control within individuals.
• To explore how task selection influences the detection of individual differences in cognitive control.

Main Methods:

• Employed a novel dense neuroimaging approach with repeated individual sampling.
• Utilized an extensive battery of cognitive control tasks.
• Analyzed within-person and between-person similarity of neural activity patterns, controlling for anatomy.

Main Results:

• Neural activity patterns for cognitive control tasks were significantly more similar within individuals than between individuals.
• These person-specific patterns remained reliable even after accounting for anatomical similarity.
• The similarity of neural activity varied significantly across different tasks, indicating task suitability for individual difference research.

Conclusions:

• Dense neuroimaging with a large task battery is valuable for understanding individual brain organization in cognitive control.
• Cognitive control neural patterns are highly person-specific and reliable.
• Task selection critically impacts the ability to discern individual differences in cognitive control.
