Desynchronization of STN-GPe neurons (1)–(4) by apLDF for different LFP thresholds. (A) The averaged order parameter $\langle R\rangle$ (filled symbols) of the STN neurons stimulated by apLDF and fraction of the stimulation time T_on (empty symbols) are depicted versus the LFP thresholds $T{h}_{\mathrm{off}}=T{h}_{\mathrm{on}}$ for different widths of the interphase gap as indicated in the legends. For zero gap the standard deviation of the order parameter fluctuations is indicated by error bars. The horizontal dashed lines indicate the corresponding values of the order parameter $\langle R\rangle$ induced by cpLDF, see Fig. 6D–F (red solid curves) for $\tau =60\mathrm{ms}$. (B) Amount of stimulation $\langle |S|\rangle$ administered by apLDF from plot (A), where the dashed lines indicate $\langle |S|\rangle$ for cpLDF. Stimulation intensity $K=10$ and delay $\tau =60\mathrm{ms}$.
