Optimal Current Transfer in Dendrites
Fig 3
Real dendrites are constrained by current transfer optimality.
(A) Scatter plots of measured radius against optimal radius and correlation coefficients for different cell classes. Different colours denote different cells of the same class. (B) Average current transfer to the root from different cell classes with (from left to right) constant, measured, and optimal radii. (C) Examples of reconstructed sample morphologies and the same morphologies with optimal diameter profiles. The neurons shown in this figure are two types of fly neurons (HS cell and VS cell with specific membrane conductance of gl = 5 × 10−4 S/cm2) and three mammalian neurons (dentate gyrus granule cells with gl = 4 × 10−5 S/cm2, and cerebellar Purkinje cells and neocortical Layer V neurons with gl = 5 × 10−5 S/cm2).
