Network synchrony creates neural filters promoting quiescence in Drosophila
This study in fruit flies shows that rhythmic, slow-wave brain activity (SWA) between specific neural networks acts as a filter for sensory information, allowing the flies to enter a quiet state similar to rest or light sleep. The filter can be 'broken' by stronger stimuli, like a puff of air, triggering a response. The research provides a detailed model of how these networks interact, with one network overriding another to control sensory processing and behavior.
