1. The document examines the relationship between brain anatomical networks and intelligence by analyzing structural, functional, and effective connectivity patterns.
2. It reviews concepts from graph theory and complex networks that are relevant for studying brain networks, including small-world networks and scale-free networks.
3. An experiment analyzed diffusion tensor images and other data from 79 subjects to construct and analyze anatomical brain networks and investigate their relationships with general and high intelligence.

3. Introduction Examines principles Structural properties Relationship between the structural substrate and dynamic functional and effective connectivity patterns The efficiency of brain structural organization may be an important biological basis for intelligence 3
13. Background – development Local spatial growth rules Preferential attachment Global network design
14. Background – clinical terms Anatomical Automatic Labeling (AAL) Magnetic resonance imaging (MRI) Diffusion MRI Functional MRI (fMRI) In vivo Cerebral cortex Tractography
15. Background - functional There are some problems in the previous work Only binary networks Nonzero connection probability value to brain region pairs which are unlikely to be connected Etc... But they all have evidence that brain network is close to small-world
16. Background - experiment 79 subjects (44 males and 35 females, mean age = 23.8 years, range = 17-33 years) intelligence quotient (IQ) test (FSIQ, PIQ, VIQ) GI (general intelligence)/HI (high intelligence) group Diffusion tensor image (DTI)/T1 image/AAL co-register Normalize, inverse Construct binary and weighted network of an individual brain Anatomical network analyses Statistical analysis
26. Future work From the computer science perspective How about the social network? Other internet overlaid networks? A brain simulator? Etc…?
