Sensory-motor integration in a nonspiking interneuron contributes to active sensor control in <i>Drosophila</i>
that encodes both mechanosensory stimuli and motor commands. We show that these neurons receive input from two classes of antennal mechanosensors, enabling responses to mechanical perturbations in both quiescence and flight. We then demonstrate how these neurons integrate higher-order motor commands with mechanosensory input to shape antennal movement. Together, this work reveals a previously uncharacterized sensory-motor circuit in the antennal mechanosensory system. These findings provide insight into how nervous systems integrate sensation with motor commands to guide the movement of active sensors, highlighting circuit mechanisms that may broadly support sensory acquisition during movement.
