Compared to Braak 0–I samples, many but not all, tau phosphorylation events are increased in native Braak III–IV samples. Normalized phospho-tau signals obtained from ELISA measurements of samples from a) entorhinal cortices (EC), b) hippocampi (Hip) and c) temporal cortices (TC). Student’s t-tests: *, p < 0.05, **, p < 0.01, ***, p < 0.001
