Postnatal maturation of DCX⁺PSA-NCAM⁺ neurons in the PL. a Maps of the location of DCX⁺PSA-NCAM⁺ cells in the PL from birth to 67 years of age, at approximately the same rostrocaudal level. b DCX⁺PSA-NCAM⁺ cells in the PL from 5 months to 24 years in coronal sections. (Right) Higher magnification of DCX⁺PSA-NCAM⁺ cells in the MPL and LPL. c DCX⁺PSA-NCAM⁺NeuN⁺ neurons in the 13-year-old MPL (Left) and LPL (Right). Some cells had the shape of migratory neurons (arrow). d Examples of DCX⁺PSA-NCAM⁺ cells that are NeuN⁺ (arrows) and NeuN^– (arrowheads) in the MPL at 13 years of age. Scale bars: 5 mm (a), 500 µm (b left), 100 µm (b middle and right), 50 µm (c), 10 µm (d)
