A, B, Relationship between song rate (number/minute) and the numbers of DCX-IR cells in HVC calculated separately for the two types of DCX-IR cells, fusiform (A) and round (B), across hemispheres (A, B) and on the contralateral (Contra; C, D) side. Individual data points from the different experimental groups are coded by different colors. Correlations were calculated using Pearson’s r. The equation for the regression line, the Pearson’s correlation coefficient r, and the associated p value are shown in the bottom right portion of each graph. PER-T, n = 7; HVC-POM T, n = 6 (one bird had damage within HVC that precluded DCX quantification; see Materials and Methods); POM-T, n = 8; HVC-T, n = 5; HVC-POM NO T, n = 4.
