Power spectra quantification and comparisons between NL-G-F and NL-NL animals at baseline. Log power graphs and power spectra comparisons of NL-G-F and NL-NL animals from 1 to 50 Hz injected at a 3 months of age and b 6 months of age from the medial entorhinal cortex and retrosplenial cortex before injection. Bar plot values correspond to quantified average of blue highlighted regions. c Baseline low gamma power spectra values before tau seeding injection in 6-month-old APP-KI animals, across multiple brain regions. Error bars are standard error of mean. Asterisks indicate significant comparisons (p < 0.05)
