Neurons are inherently plastic, adjusting their structure, connectivity and excitability in 20 response to changes in activity. How neurons sense changes in their activity level and then 21 transduce these to structural changes remains to be fully elucidated. Working with the 22 Drosophila larval locomotor network, we show that neurons use reactive oxygen species 23 (ROS), metabolic byproducts, to monitor their activity. ROS signals are both necessary and 24 sufficient for activity-dependent structural adjustments of both pre-and postsynaptic 25 terminals and for network output, as measured by larval crawling behavior. We find the 26 highly conserved Parkinson’s disease-linked protein DJ-1ß acts as a redox sensor in neurons 27 where it regulates pre-and postsynaptic structural plasticity, in part via modulation of the 28 PTEN-PI3Kinase pathway. Neuronal ROS thus play an important physiological role as 29 second messengers required for neuronal and network tuning, whose dysregulation in the 30 ageing brain and under neurodegenerative conditions may contribute to synaptic 31 dysfunction. 32
