Separation angle depends on the high-threshold calcium channel conductance: polar plots of averaged firing frequency for 30 simulations with small Iinj variations (in 0.001-nA steps) for CW and CCW simulations for gL = 0.00022 S/cm2 (A), gL = 0.0001 S/cm2 (B), and gL = 0 S/cm2 (C). The separation angles are 7.21°, 5.40°, and 4.53°, respectively.
