Flux rates were determined by counting the numbers of APP-EGFP particles that crossed a defined line within the mid-section of axons as previously described by us and others (8, 9, 46).
Pyramidal neurons with diffuse cytoplasmic tau reactivity, often with a defined line around the nucleus (Fig. 1b, neurons 4) and previously described in association with AGD [ 36], seen in the hippocampal areas CA1, CA2 and CA3 were also not included in assessments for this study.
