Kyushu University finds adolescent brains form dense synapse clusters, challenging pruning theory

Researchers at Kyushu University used super-resolution microscopy and SeeDB2 to map mouse brain neurons, discovering high-density synaptic hotspots forming during adolescence, not early development.
Mutations in schizophrenia-linked genes disrupted this adolescent synapse formation, suggesting impaired cluster growth may contribute to the disorder, shifting focus from excessive pruning to faulty synapse building.
The study, published in Science Advances, highlights that adolescent brain development involves both pruning and targeted synapse formation, though it remains unclear if similar mechanisms occur in humans or primates.
Does this mouse study mean the long-held theory of 'adolescent synaptic pruning' is now obsolete?
Could we one day scan a teen's brain for these 'hotspots' to predict future mental health risks?
Could teenage lifestyle choices permanently impair the brain's ability to build crucial problem-solving circuits?
If the teen brain builds 'synaptic hotspots,' should we fundamentally redesign high school education?
Is schizophrenia caused by the brain failing to build new connections, not just trimming old ones?
What other textbook facts about the brain are wrong, just waiting for new technology to disprove them?
