Soma size and total dendritic length varied as a function of bird age. (A) Mean (±SEM) cross-sectional soma area of HVC-RA and LMAN-RA cells. In HVC, the average soma size in 3-month-old birds (black bars) was significantly larger compared to 6- (grey bars) or 12-month-old (white bars) individuals (p≤0.004). In LMAN, the average soma size in 3-month-old birds was significantly larger compared to 12-month-old individuals (p= 0.003). (B) Mean (±SEM) total dendritic length of HVC-RA and LMAN-RA cells. In HVC, the average total dendritic length in 12-month-old birds was significantly greater compared to 3- or 6-month-old individuals (p≤0.02). In LMAN, the average total dendritic length did not significantly vary across the three age groups.
