(B) Cells residing in the inner granule cell layer with single dendritic extensions were classified as young cells, whereas those with multiple dendrites that resided in the outer cell layer were classified as mature. Scale bars: 50 μm. (C) Dendritic tracing of a young neuron and (D) Dendritic tracing of a mature neurons by using the software Neurolucida.
