TABLE 3.

Weights of synaptic connections in the network

Target population (location)	Excitatory drive {weight of synaptic input} or source population {weight of synaptic input from single neuron}
Ramp-I (rVRG)	drive(pons) {2.0}; early-I(2) {−0.275}; pre-I {0.06}; aug-E{−2.0}; post-I {−1.0}.
Early-I(2) (rVRG)	drive(pons) {1.7}; aug-E {−0.25}; post-I {−1.0}.
Pre-I (pre-BötC)	drive(pre-BötC) {0.3}; drive(RTN/BötC) {0.13}; drive(pons) {0.55}; pre-I {0.03}; aug-E {−0.025}; post-I {−0.225}.
Early-I(1) (pre-BötC)	drive(RTN/BötC) {0.7}; drive(pons) {1.1}; pre-I {0.034}; aug-E {−0.145}; post-I {−0.4}.
Aug-E (BötC)	drive(RTN/BötC) {1.0}; drive(pons) {0.4}; early-I(1) {−0.115}; post-I {−0.32}.
Post-I (BötC)	drive(RTN/BötC) {0.1}; drive(pons) {1.5}; early-I(1) {−0.04}; aug-E {−0.01}.
Post-I (e) (BötC)	drive(RTN/BötC) {0.1}; drive(pons) {1.0}; early-I(1) {−0.2}; aug-E {−0.15}.

Values in figure brackets represent relative weights of synaptic inputs from the corresponding source populations (w_ji) or drives (w_dmi); see Eq. 7. Abbreviations: ramp-I, ramp-inspiratory; rVRG, rostral ventral respiratory group; early-I, early-inspiratory; pre-I, preinspiratory; pre-BötC, pre-Bötzinger Complex; aug-E, augmenting expiratory; post-I, postinspiratory.
