title: Stability of dendrites in cortical barrels of C57BL/6N mice between 4 and 45 months.
abstract: Qualitative and quantitative studies of dendritic parameters were conducted on Golgi-impregnated layer IV spiny stellate neurons in the posteromedial barrel subfield (PMBSF) of somatosensory cortex of the C57B1/6N mouse. Three mice each, at 4, 12, 22, 26, 30, 36 and 45 months of age were studied. No qualitative changes were observed among animals of different ages. The quantitative data indicated that dendritic length and numbers of segments remained unchanged over all ages studied.
