Scientists at the University of Notre Dame studied how our brains work together to make us intelligent. They found that intelligence is not just about specific brain networks, but about how these networks communicate and process information.

Modern science often looks at the brain as a collection of specialized systems. Each system has its own job, like attention or memory. But scientists have struggled to explain how all these separate systems work together to make us intelligent. Researchers at the University of Notre Dame set out to solve this mystery.

They used advanced brain imaging techniques to study how the brain is organized overall and how that organization gives rise to intelligence. The team, led by Aron Barbey, found that general intelligence is not just about a specific brain region or function. Instead, it's a property of the brain as a whole.

The researchers proposed a new framework called the Network Neuroscience Theory. This theory suggests that general intelligence emerges from how efficiently the brain's networks are structured and how well they work together. They tested this idea by analyzing brain imaging data from 831 adults and cognitive performance data from an independent group of 145 adults.

Their findings showed that the brain is organized in a way that allows different networks to communicate and process information effectively. This coordination is what makes us intelligent, not just one specific brain region or function.

Why It Matters
