" ...In this study, we demonstrate that the LGMD (Lobula Giant Movement Detector) neuron exhibits a large M current, generated by noninactivating K channels, that shortens the temporal window of dendritic integration, regulates a firing mode switch between burst and isolated spiking, increases the precision of spike timing, and increases the reliability of spike propagation to downstream motor centers. ..."
