Membrane potential changes related to coughing and swallowing in an ILM during SLN stimulation (arrowheads). Note the depolarization during the inspiratory phase of coughing (C1), followed by abrupt hyperpolarization at the I–E transition (C2), transient hyperpolarization (C3), and gradual repolarization during the residual abdominal burst (C4). This neuron hyperpolarized abruptly during the swallow-related hypoglossal burst (SW2) and then depolarized inSW3. Presumptive resting potential of this ILM was measured at the arrow.
