The graph of the function corresponds to the linear IF model with , , and . The function is concave-down for and concave-up for .
(a) A fires; (b) B about to fire; (c) B fires.
“Snapshot” clustering behavior at a given time in a population of linear IF oscillators [ ]. Each dot represents the phase of one oscillator.
Fraction of traveling oscillators in a population of linear IF oscillators as a function of the coherence parameter . The fraction is 2% over the range .
Total clustering in a population of linear IF oscillator for strong coherence . Each dot represents the value of every firings. The single dot per oscillator indicates a phase-locked configuration (transient behavior is not shown).
Partial clustering in a population of linear IF oscillators for intermediate coherence . Dots have the same meaning as in Fig. 5 . Oscillators 17 and 91 are traveling while the 98 remaining oscillators are nearly phase-locked.
Weak clustering in a population of linear IF oscillators for small coherence . Dots have the same meaning as in Fig. 5 . About half of the oscillators are traveling and the level of clustering becomes weak.
Firing period and values and for various values of the coherence parameter with , , , , , . In the current case, the number of clusters .
