Figure 6. Phase Response-Variance Curves (PRVCs); Variance of stimulus-evoked shifts in spike timing is phase dependent.

Figure 6

A. PRVCs (for low-, mid-, and high-gain synaptic backgrounds in A1, A2, & A3, respectively) illustrating the variance of spike shifts evoked by somatic stimulation of GPbase contain a single peak that diminishes across spike cycles. Variance of shifts in spike timing was near zero when stimuli were delivered coincidentally with a spike in the control spike train (phases of 0 and 1). B. PRVCs for distal dendritic stimulation of GPbase are multimodal in the higher order intervals (F2–F5) reflecting multiple sources of variability. C. Like the PRVC for somatic stimulation of GPbase, the PRVC for distal dendritic stimulation of GPNDSK contains only a single peak, indicating that dendritic SK conductance accounted for variance peaks early and late in the F2–F5 PRVC for dendritic stimulation of GPbase.
