Summary of determined GC parameters (mean ± SEM, or mean with 16–84% confidence interval in brackets). The input resistance (Rin) was obtained with somatic or direct dendritic patch-clamp recordings. The diameter of the soma and the length of the dendrites were measured from stacks of two-photon images. The diameter of the dendrites, the specific membrane resistance (Rm), the dendrite-to-soma conductance ratio (ρ) and the electrotonic length of the dendrites (L) were determined in Figure 3C.
