The CV and AE motoneurons are electrically coupled. Paired recordings of an AE and a CV motoneuron showing the effect of injecting a square current step in one of the neurons, as the ganglion was bathed in a solution with a high Mg²⁺/Ca²⁺ ratio.A, The AE motoneuron was stimulated with a + 3nA pulse (top panel) or a −3 nA pulse (bottom panel). B, The CV motoneuron was stimulated with a +3 nA pulse (top panel) or a −3 nA pulse (bottom panel). Qualitatively similar recordings were obtained for another five pairs of AE and CV neurons.
