proBDNF protein in song control nuclei.
Data and representative images are from the punches of LMAN (top) and RA (bottom). The ratio of proBDNF/actin was calculated from mean optical densities of bands in each individual. Values represent means+one standard error. Symbols indicate significant differences as follows: a = main effect of treatment; * = main effect of sex; # = control males greater than control females; + = E2 females greater than control females. Sample sizes are indicated at the bottom of each bar. Representative bands for each protein from the LMAN and RA of each group are shown above the histograms.
