Fig. 1B. Computer-averaged connective spike (30 iterations) of cell SE1 recorded extracellularly in the ipsilateral connective between M14 and M15 (bottom trace; C(14,15)). The averaging program was triggered from a spike recorded intracellularly from the soma of cell SE1 (top trace). The slight rise in the middle of the top trace was due to the periodic occurrence of a second spike in cell SE1 that was subsequently averaged out. In this and all succeeding figures, the letter in parentheses indicates the location of the neuronal cell body, either the right (R) or left (L) side of the subesophageal ganglion or segmental ganglion, while the number indicates the segmental ganglia from which the recording is made.Return to Results
