In the original version of Table 1 associated with the review article “Modeling α-Synuclein Propagation with Preformed Fibril Injections”, the “amount of PFF injected” for the Rey et al. 2018 paper should be “0.8 μg of 5 mg/ml” instead of “8 μg 1 mg/ml”. The injection site mentioned in the “amount of PFFs injected” for Breid et al. 2016 paper should be “intraperitoneal” instead of “intramuscular”. The “amount of PFFs injected” for the Manfredsson et al. 2018 paper should be “6×5 μl” instead of “5 μg”. Additional information on the concentration of PFFs was added for Breid et al. 2016 paper and Durante et al. 2019 paper, being “1 μg/μl” and “1 mg/ml”, respectively.

The table describes the sites of preformed fibril (PFF) injection, the ages of the animals, the amount of seed, and the duration or time points sample analysis used in the experiments. WT: wild type, GFP: green fluorescent protein, LPS: lipopolysaccharide, IC: inferior colliculus, CPu: caudate putamen, NTG: non-Tg.

In the first paragraph of the “SYNUCLEINOPATHIES IN PERIPHERAL PFF INJECTION MODELS” section, we included the description olfactory bulb injection. However, this content belongs to the “SYNUCLEINOPATHIES IN INTRACEREBRAL PFF INJECTION MODELS” section.
