Electroencephalographic signature in adult PXR−/− mice. Each data point corresponds to a 0.5-Hz range, as indicated on the X axis. (A) During sleep periods PXR−/− mice displayed reduced 5–10-Hz EEG activity (theta waves, gray shadow). (A1) Theta frequency were similar between PXR−/− and WT mice during awake-exploration periods. Interestingly 0.5–4-Hz (delta) waves were generally increased in PXR−/− mice. (B, B1) No differences were measured at Hz > 20 (C–C1) Examples of EEG and time-joint frequency analysis showing decreased theta in PXR−/− during sleep (arrows). (D–D1) Example of delta bands in PXR−/− mice.
