Plot of average ΔC m versus step duration (step to –10 mV; black circles and straight lines; 9 cells; mean ± S.E.). The plot was approximated by summing two components, a bi-exponential fit to the rise at early times (blue circles and lines) and a linear fit to the ΔC m values between 0.2 and 1.0 s (green points and line). The steady replenishment rate was obtained from the slope of the green line (37.6 ± 3.7 fF-s –1 ). Cone silhouette republished from Neuron, Vol 91, Grabner, C. P. et al.
