Phasic current injection is insufficient for phase lead induction. A: phasic current injection (Iinj) to modeled neuron, applied with linearly increasing/decreasing amplitudes: 0.04 nA (1st and 5th), 0.08 nA (2nd and 4th), and 0.12 nA (3rd injection). Bottom panels represent the evoked spiking with high-threshold calcium channel conductance of gL = 0 S/cm2 (left), gL = 0 S/cm2 and gM = 0 S/cm2 (center), and gL = 0.00022 S/cm2 (right). B: phasic current injection (Iinj) to modeled neuron, applied with the following amplitudes: 0.105 nA (1st and 5th), 0.115 nA (2nd and 4th), and 0.125 nA (3rd injection). Bottom panels represent the evoked spiking with high-threshold calcium channel conductance of gL = 0 S/cm2 (left), gL = 0 S/cm2 and gM = 0 S/cm2 (center), and gL = 0.00022 S/cm2 (right).
