Classic cadherin expressions balance postnatal neuronal positioning and dendrite dynamics to elaborate the specific cytoarchitecture of the mouse cortical area

•We confirm expression profiles of classic cadherins in the mouse barrel cortex.•We generate a resourceful transgenic mouse illuminating nuclei of barrel neurons.•A conditional electroporation method allows us to test postnatal roles of cadherins.•Cadherins are involved in elaboration of the barrel area specific cytoarchitecture.•Activity dependent machinery might modulate the cadherin expression profiles.
