Figure 3 - Neuronal swallowing patterns.

a: Activity of an oropharyngeal neuron (SwN) recorded within the sheep NTS during swallowing. Single-pulse stimulation to the ipsilateral SLN elicited an initial synaptic response in the form of one short latency spike, followed by the swallowing burst firing when swallowing occurred (mylohyoideus muscle EMG: MH m). b: Neuronal firing (SwN) elicited in an oropharyngeal neuron with preswallowing discharge, in response to stimulation of the ipsilateral SLN (recorded from the sheep NTS). Note that the neuron exhibited only the preswallowing discharge when no swallowing was elicited. (Source: Adapted from Ciampini and Jean³⁷ and Jean.⁶,with permission)
