Figure 5.

Correlations between EEG delta power and motor activities in non-rapid eye movement (non-REM) sleep. The plots and statistical analyses show the relationships between electroencephalogram (EEG) δ power and tonic (A and B) and within-breath phasic (C and D) tongue motor activity, postural (neck) electromyogram (EMG) activity (E and F), respiratory rate (G and H), and diaphragm amplitude (I and J). The individual data points show raw values (left) and values normalized to the vehicle controls (i.e., Vehicle₁ and Vehicle₂) within each animal across the experimental conditions (right).
