Brain Connectivity and Intelligence: A Comprehensive Magnetic Resonance Imaging Analysis Illuminating the Neural Underpinnings
Motivation: To the best of our knowledge, no study in neuroscience has been conducted based on high intelligence (HI) and low intelligence (LI) groups young healthy adults. Goal(s): This study aims to explore the effect of brain network structures on the intelligence quotient and brain efficiency of healthy adults. Approach: We focused on the white matter’s topological traits, which demonstrate network performance and structural connectivity differences between the HI and LI groups. Results: We found structural differences in connections between specific nodes in the HI and LI groups. Intelligence correlated positively with network efficiency and negatively with path length. Impact: This study innovatively explores the relationship between brain network structures and intelligence in healthy young adults. This study revealed that higher intelligence is associated with efficient brain networks and greater resilience in targeted network disturbances.
