Overview of experimental design and analysis. (a) Visual timeline of experimental animal cohorts and initial number of animals in each cohort. Mice were instrumented with an electrophysiological montage and cannula or only a cannula at least 2 weeks prior to AD-tau seed injections. Mice were subsequently injected at 90 or 180 days after birth with AD-tau or buffer solutions and sacrificed or recorded at different timepoints (m.p.i. refers to months post injection). (b) Histological evaluation of pathology was carried out using brain clearance and immunohistological staining, followed by light-sheet imaging and image segmentation and quantification. (c) Sagittal illustration of the recording montage and analysis pipeline prior to quantitative analysis.
