Figure 7.

Bar graphs illustrating transneuronal infection of neurons within the IN and IL/PL medial prefrontal cortices (normalized to AP infection within each case) in control NH/NS rat pups injected with virus on P4 or P8 and killed on P6 or P10, respectively, and in 15 min and 3 h H/S rat pups injected with virus on P8 and killed on P10 (group mean ± SE). Within each region, bars with different letters (i.e., A, B, or C) are significantly different (p < 0.05). Statistical comparisons were performed on log-transformed data that met assumptions of normality and homoscedasticity (see Results).
