Local slopes (S) between time points from the corresponding kinetics of loop-DNA digestion of neuronal nucleoids from different post-natal ages. Topological zones relative to the NM (Fig. 3) were established according to such local slopes. New-born (P0), 7-day-old (P7), adult (P80), old (P540) rats.
