cONv and OFFv deliver synchronous output to prothoracic networks. All data are from one continuous experiment. A, Intracellular cONv and neck-connective recordings during SP joint movement (bottom). B, Spike-triggered average of the intracellular cONv recording using either the intracellular (magenta) or the extracellular cONv spike (black) as the trigger. Right, Both averages were overlaid, revealing identical time courses. cONv spikes can be extracted from the neck-connective recording with >99% reliability. C, Intracellular OFFv recording (top), with the simultaneous neck-connective recording (middle, magenta) showing cONv spikes in response to antennal deflection (bottom). D, Mean spike rate of OFFv during ramps with different velocities. E, Mean spike rates of OFFv (black) and cONv (magenta) with the respective spike trains (vertical lines in the middle traces) and the stimulus (bottom). Spike rates were averaged within a 33 ms sliding window. F, Cross-correlation of cONv and OFFv spike rates, as shown in E, within a 145-s-long time window. Spike rates were normalized by subtracting the median rate.
