A new type of brain imaging scanner shows that intelligence is strongly influenced by the quality of the brain's axons or wiring that sends signals throughout the brain. The faster the signaling, the faster the brain processes information. And since the integrity of the brain's wiring is influenced by genes, the genes we inherit play a far greater role in intelligence than was previously thought.
