Pro-growth gene expression in neuronal tissues expressed a fold change of mRNA level compared to ENT control. (A) Hippocampus levels of bdnf, ngf, c-fos, and egr1 after 22 days treatment with ENT, IL, SMOF or EXP diet. (B) Frontal cortex levels of bdnf, ngf, c-fos, and egr1 after 22 days treatment with ENT, IL, SMOF or EXP diet. Data are presented as mean ± SEM. * P < 0.05 ENT v IL
