There was also a trend toward differences in category 3 cells, and while it failed to reach significance [ F (3,18) = 3.141, p = 0.057], the group effect size (Cohen’s f = 0.7262) suggests that the lower number of category 3 cells in HRM/DISC1 hippocampi may be of interest. 2.7 Reduced dendritic spine density in HRM/DISC1 hippocampal dentate granule cells To further investigate the effects of reelin and DISC1 disruption on dendritic spines, we used Golgi-Cox staining to visualize a subset of neurons and counted dendritic spines in dentate granule cells (DGC) and hippocampal pyramidal cells (HPC) ( Figure 8A ).
