Local synaptic inputs support opposing, network-specific odor representations in a widely projecting modulatory neuron
Serotonin plays different roles across networks within the same sensory modality.Previously, we used whole-cell electrophysiology in Drosophila to show that serotonergic neurons innervating the first olfactory relay are inhibited by odorants (Zhang and Gaudry, 2016).Here we show that network-spanning serotonergic neurons segregate information about
