Figure 1

Median power spectra for control, BSE-negative challenged/suspect and BSE-positive cattle after frequency domain analysis. The median power spectrum is the grand median of the power spectra from all animals in each group, calculated from the power for each frequency (in 0.005 Hz steps). BSE-negative cattle were cattle experimentally challenged with material from BSE-exposed or BSE-positive cattle or clinical field suspects, which were not confirmed as BSE cases by postmortem tests. BSE-positive cattle were cattle with a postmortem test diagnosis consistent with BSE.
