Scheme II processing of the temporal series and the power spectra for the difference between residence times on the (r, f)-plane.

(a) Temporal series showing winnerless sequential alternation of activation between different neurons for Eq. 1. (b) Temporal behavior of the time spent in the vicinity of the saddle point , . Note the complex variability of the saddle residence times. (c) Difference between residence times according to scheme II . (d) Power spectrum for a temporal series as in (c). (e) Power spectra for the set of r values satisfying necessary and sufficient conditions for winnerless competition and a parameter step . (f) Zoom on the subset of values and a parameter step .
