The different rates at which β-amyloid (Aβ) was cleared from the brains of mice that were awake, sleeping, or in an induced sleep state using the anesthetic ketamine/xylazine (KX). The * indicates a P value < 0.05, meaning that the differences in clearance rates are statistically significant in this study. The error bars represent standard error of the mean.
