Figure 8 - Activity of cortical neurons during swallowing.

a: Repetitive stimulation of ipsilateral SLN induced rhythmic swallowing (MH m) (1). Note that the burst firing is elicited at each swallow. Activation of the same neuron during spontaneous swallowing (2). b: Discharge of a cortical cell activated by SLN stimulation (dots). Each SLN stimulation induced a short latency response of the cortical neuron (cN), which also fired during swallowing. Note the blockade of the synaptic response during the burst firing (collision).
