Figure 13 illustrates the effects of prenatal exposure to VPA, showing that HDAC inhibition may exacerbate oxidative stress by dysregulating the expression of genes involved in the antioxidant response, thereby promoting redox imbalance through increased ROS production and impaired antioxidant defenses (Gottlicher 2001
Quantitative morphometric analysis using confocal microscopy and fluorescent markers (such as GFP or anti-MAP2 immunostaining) reveals both an increase in total spine number and a shift toward mature, mushroom-shaped spine morphology
