Fig. 3. Obesogenic diet and prolonged NRG1 administration interact to influence hippocampal volumes.
A, B Total hippocampal volume (both left and right hippocampi combined) were affected by the treatment [F(1, 19) = 9.48, p = 0.006]. Subchronic NRG1 administration during adolescence resulted in significant total hippocampal volume reduction (CDV vs. CDN, p = .003). C, D Hippocampal subfield segmentation showed a significant interaction [F(1, 19) = 6.44, p = 0.020] effects on CA1 region. WDV rats had a significantly smaller CA1 volume than CDV rats (p = 0.015). Sample size = 6 rats/group.
