Note: No significant difference in the relative coordinates of the synapses form by each L1–3 interneuron group on L5a and L5b pyramidal neurons (P > 0.05; Mann–Whitney rank-sum tests). The coordinates are present as mean ± SEM (±2SD, which represents of the distribution range of 72.8% of data points).
