-
↵a The horizontal span and height of dendrites were measured in the frontal plane to which all the dendrites were projected.
-
↵bTotal length of axon collaterals was estimated by multiplying the total length of axon collaterals projected onto the frontal plane by π/2.
-
↵cTotal number of boutons in L4–6 were counted and those in L1–3 were estimated from length of axon collaterals and bouton density in L1–3 (L2/3 neurons, 224.2 ± 39.0 /mm; L4 neurons, 269.6 ± 38.3 /mm; L5a neurons, 229.8 ± 52.7 /mm; L5b neurons, 200.5 ± 37.6 /mm).
