From: From sleep staging to spindle detection: a case study on end-to-end automated sleep analysis

Boxplot of spindle densities for fast spindles (frequencies > 13 Hz) as detected by the SUMOv2 model in the BD recordings for healthy controls (HC) and patients with bipolar disorder (BP). Spindles were detected in N2 sleep annotated by the RSN model. The labels above the boxplots indicate the mean and standard deviation of the spindles per minute (SPM) for each cohort and channel.
