GLMMs (Poisson distribution) or LLMs (normal distribution)
dependent on the data distributions for latency variables to unconsciousness
(F50 b 12.7 Hz (non-responsive state); and b6.8 Hz
(general anaesthetic plane); latencies to visual inspection characteristics
(presence of slow-wave and 3 consecutive isoelectric 2 s epochs);
latencies for the signal to have a total power equal to 10% of baseline;
and finally latencies to isoelectric (PTOT b170 mv and F50 N22 Hz).
All models included bird ID and triplet number as random effects. All
fixed effectswere treated as factors and all interactions between factors
were included in maximal models.
