Figure 3. Sleep scoring performance of artificial neural network.

Figure 3

(A–B) Example hypnograms from an individual rat depict behavioral state as characterized by manual or algorithmic scoring, respectively. Bottom bar depicts the 12/12 h daily light cycle. (C) Quantification of algorithm accuracy, sensitivity, and specificity for example data presented in (A). (D) Accuracy, sensitivity, and specificity of algorithmic scoring across all days (N = 40 total from nine rats). Acc—Overall model accuracy; W—Waking; NR—NREM sleep; R—REM sleep.
