Area 7a dendritic length and branching are not affected by aging. A–C, Representative tracings from young (A), AU (B), and AI (C) animals. Black represents basal dendrites. Red represents apical dendrites. D, No age-related changes were seen in total dendritic length or when either basal or apical dendritic length was analyzed separately. E, No age-related changes were seen in total dendritic branching or when either basal or apical dendritic branching was analyzed separately.
