Dendrites are neither attracted nor repulsed by pinwheel centers. A, Schematic showing the relationship between biases in the angular distribution of dendrites around the soma and the angle α between the resultant vector of the dendritic tree envelope (thick black arrow) and the direction toward the nearest pinwheel center (red arrow). B, Angle α as a function of the distance between soma and pinwheel center. C, Equivalent analysis as shown in B, except that the resultant vector was computed based on the distributions of dendritic lengths.
