Fig. 3. (A-E) Morphological analyses of cerebellar sections from BTBR T+tf/J (BTBR) and C57BL/6J (B6) mice. The numbers of Purkinje cells were quantified in folia 2, 4, and 8. Photomicrography of cerebellar sections are from C56BL/6J (A, B) and BTBR T+tf/J (C, D). No significant difference was observed in either BTBR or B6 mice (H&E stain, ×20).
