Fig 1. Example of two NTS Inspiratory neurons during breathing and swallow.

Unsorted and sorted spike trains, and instantaneous firing frequency (FF) (Hz) are displayed; demonstrating an increase in FF during swallow. The swallow is outlined in the gray box. See Table 2 for anatomical location and Table 1 for neuron discharge pattern definitions. Recordings of EMG moving averages from the mylohyoid, thyrohyoid, parasternal, diaphragm and esophageal pressure are also shown.
