Figure 7

Propagation of slow-waves during non-rapid eye-movement (NREM) sleep and isoflurane anesthesia: The red underlined episodes in Figure 2C are visualized in a sequence of image plots where pixels represent electrode sites and electrical potential is coded in color. Slow-wave propagation patterns during (A) NREM sleep and, (B,C) 1.5 and 3.0% isoflurane anesthesia. LFP (local field potential) activity generally initiates along the diagonal of the recording plane, corresponding to IHA/HI, and propagates mostly within the diagonal under all recording conditions. LFP voltage scale differs across subfigures (A–C).
