Unbiased stereological quantification of α-synuclein. Graphs (mean ± SEM) represent α-synuclein-positive cells/mm3 in OB (a), AON (b) and Pir (c). In graph b, arrow indicates counted aggregates in WT, which were only observed in the α-synuclein injection site (dashed square). T-test differences were regarded as statistically significant at #P < 0.05 and ###P < 0.001. For statistical data, see Additional file 4: Table S8. For abbreviations, see list
