Estimations of the total numbers (±SEM) of PNN, of PV-positive cells and of PV cells surrounded by PNN in the HVC, RA and Area X of zebra finches, canaries and starlings based on average volumes of these nuclei measured in 3 zebra finches, 3 canaries and 7 starlings used in the present experiments. Species differences were analyzed using 1-Way Kruskal-Wallis ANOVA. astatistically different from b(p<0.05) by post hoc multiple comparison.
