Figure 4. State dependent modulation of breathing in urethane anesthetized mice.

Figure 4

A) Long-term EEG recording at the HPC site and corresponding respiratory frequency (breath per minute, BPM) and rectified and integrated activity of intercostals (INT), genioglossus (GG) and abdominal (ABD) muscle EMG activity across spontaneous brain state alternations. Schematic block at the bottom of the plot indicate time spent in REM-like (grey), transition (white) and SWS-like (black) states. B) Details of the HPC trace, BPM and raw and integrated traces of INT, GG and ABD EMG in REM-like (left), transition (centre) and SWS-like states.
