Description
Arshiya Sangchooli and co-authors tracked how visual pathways to the brain's alarm center mature in adolescence, in a 2026 study. The amygdala can receive visual news by a fast deep route and by a slower cortical route. Whether the fast route truly exists, and how both routes grow, has been debated. The team used advanced diffusion imaging from a huge adolescent study, with over four thousand participants.
Their reconstructions support the deep route on both sides of the brain. Cortical visual tracts grew stronger with age and puberty. The deep route, by contrast, weakened as puberty advanced. Stronger links in either route went with faster responses on a visual task. The authors say the two routes trade strength across early adolescence, a shift that may shape emotional reactions.
