Scatterplots of associations with hippocampal activity. A, The T1-weighted slice illustrates fMRI activity in the hippocampus (p < 0.05, FDR-corrected). B, Scatterplot of hippocampal activity and neocortical amyloid-β (PiB). C, Scatterplot of hippocampal activity and entorhinal tau (AV1451). D, Scatterplot of hippocampal activity and inferior temporal tau. The line indicates the best fit for a linear regression model. R denotes the correlation coefficient, N = the number of observations. p = p-value.
