Additionally, we examined Iba1 + cellular densities on PND60 and found a significantly increased density of Iba1 + cells in deep layers of MO and IL of young adult MD rats (W1,11 = 44.974, p < 0.001 and W1,11 = 11.819, p < 0.001, respectively), while no differences were found in superficial MO, superficial IL, roCg1, PrL or roVLO (Figure 6). Here, PRL is linked to Menkes disease.
