Robustness of respiratory rhythm generation across dynamic regimes
Fig 7
Network oscillation mechanisms when pre-I is intrinsically tonic, with c11 = 0.01.
Mechanisms are identical to the case when pre-I is intrinsically oscillatory. (A) Analogous curves to Fig 6A. Maximal inhibition is 0.088 (black square), minimal inhibition is 0, inhibition at escape is 0.012 (black circle). Note that the grey curve of knees terminates, which corresponds to where the Vpre−I-nullcline becomes monotone. (B) Analogous curves to Fig 6B. The termination of the curve of left knees is also evident here (around inhibition of 0.7 ×10−2).
