The electrophysiological data were obtained with double recordings from the soma except for cell 8, for which somatodendritic double recordings were used. Stochastic error attributable to recording noise was assessed using a bootstrap method, and variability of best-fit parameter values is given by the CV. Surface area includes somatic, dendritic, axonal, and spine membrane.
