TI Comparison of EEG and ECoG for detecting cerebrocortical activity during slaughter of calves

PT journal article

AB Parallel electrocorticograms (ECoG) and electroencephalograms (EEG) were recorded during stun-recovery and stun-slaughter of eight calves 4-6 weeks old. Epochs of 8.2 s duration were compared for differences in power content and frequency distribution using Fast Fourier Transform analysis. During exsanguination, the mean rate of decline in the ECoG power content was 0.025 log units/s, three times faster than the mean rate of decline of the EEG at 0.008 log units/s. The duration of the electroplectic fit post-stun was detected equally well by the two techniques. The slower rate of decline in the power content of the EEG during slaughter means that the time to onset of isoelectric cortical electrical activity will be longer if determined by EEG measurements than by ECoG recording.
