Quantitative analyses of p-trk immunoreactivity in hippocampal subregions of stimulated and unstimulated WT, heterozygous, and null (trkBshc) mutant mice. The data are the mean ± SEM of the percentage reduction in gray value in the given subregions compared with corpus callosum (see Materials and Methods); high values reflect more intense immunoreactivity. *p < 0.05 compared with unstimulated WT mice; φp < 0.05 compared with kindled and stimulated WT mice (one-way ANOVA with post hoc Bonferroni's test).
