## Abstract Previous serial EM studies of the anterior nerve cord of amphioxus larvae implicate the third pair of large paired neurons (LPN3s) as key components of the pacemaker responsible for oscillatory premotor output in somites 1 and 2. Here the synaptic relationship between the LPN3s and a fo
