Scientists find hidden synapse hotspots in the teen brain: Study

Summary

Scientists discovered that the adolescent brain forms dense new synapse clusters in specific neuron parts, challenging previous beliefs about synaptic pruning and suggesting implications for schizophrenia.

Key Points
  • Scientists found that the adolescent brain actively builds dense synapse clusters in specific parts of neurons, not just pruning old connections.
  • These synapse hotspots emerge during adolescence and may influence higher-level thinking and brain function.
  • Disruption in forming these synapses during adolescence may contribute to conditions like schizophrenia.
  • The study used advanced microscopy and tissue clearing techniques to map synaptic changes in mice brain Layer 5 neurons.
  • Researchers highlight the need to reconsider the traditional 'synaptic pruning' hypothesis in adolescent brain development.
