Ordering neurons by distance to principal axis origin reveals significant relationships between neuronal position and basal dendritic morphological properties.

Linear regressions used distance to principal axis origin as the x-value, and the morphological parameters in each row as the y-value. Definitions of morphological parameters as in Table 1. N = 116 neurons.
