Figure 1 Telemetric recordings of the ferret gastric myoelectric activity and spectral analysis. A: The raw trace sampled at 1 kHz; B: The same trace after filtering (low pass filter, cut-off: 0.3 Hz; sampling frequency 10 Hz); C: The fast Fourier transform of the same 5 min of data (Hann window, 2048). DF: Dominant frequency; DP: Dominant power; cpm: Counts/min; Total power: Total power contained in all the frequency bins between 0 and 18 cpm.
