From a ventrolateral soma, it crosses the midline and extends laterally and posteriorly, with predominantly contralateral pre- and post-synapses (Kohsaka et al., 2019; Zarin et al., 2019). Its input synapses are mainly in the same neuromere as the soma and its output synapses are mainly in the next posterior neuromere (Kohsaka et al., 2019). It outputs onto a set of contralateral transverse motor neurons, including MN-LT1-4 (Zwart et al., 2016) as well as other premotor neurons (Kohsaka et al., 2019). It is specifically involved in forwards locomotion (Kohsaka et al., 2019). larval T01d3 neuron larval A01d3 neuron FBbt:00111732 eIN-3 intersegmental feedback during forward propagation VFB:FBbt_00111732 fly_anatomy.ontology Ifb-Fwd A01d3 renamed to A01d2 in Mark et al.
