Figure 3 - Influences of phase delay shifts of light and food restriction on blood pressure and heart rate in telemetry monitored rats

Figure 3. (Colour online) Actogram and spectrogram (spectral power) visualisation of heart rate (HR), systolic blood pressure (SBP) and locomotor activity (LA) in freely moving rats exposed to moderately increased salt intake (SL) or time-restricted food (FR) in combination with control (LD) or delay shifts of light (PDS). Notes: Actograms were made from raw data by Chronos-Fit. The 2D surface graphs (spectograms) were created from significant periods (0-30 h) in Matlab. In spectrogram, the intensity of rhythm at a particular period was expressed with different colours. The lowest spectral power is indicated by blue and the highest by red. Numbers at the colour scale indicate spectral power of measured parameter.
