Table 3. Neurons recorded from the dorsomedial medulla described by neuron discharge identity; depth; coordinates for medial-lateral (ML); rostral-caudal (RC); the maximum peak-to-peak firing frequency (FF; in Hz) during breathing and swallow; and direction of change.
Neurons are arranged by discharge identity (see Table 1 for descriptions) and the NTS/dorsal respiratory group neurons (< 2500 μm depth) are italicized. Neurons displayed in Figs are noted under the identity column.
