Scientists have mapped the genetic architecture of the brain’s communication bridge, the corpus callosum, using AI and MRI data from over 50,000 people.
The study uncovered dozens of genes that shape this vital structure’s size and thickness, many active during prenatal development when the brain’s wiring is established.
Differences in these genes may explain why changes in the corpus callosum are associated with mental and neurological disorders.
The team’s open-source AI tool now enables global researchers to analyze brain structure faster and with unprecedented precision.
