I need just a simple explanation of the figures & tables;I understand x.y.z variables but what is the graph trying to say;


Figure 1. EEG profiles (squares) of individual ‘Am’ before, during and after an arousal, plotted against metabolic rates (triangles) and ambient temperature (diamonds). REM: rapid-eye movement stage, NR: non-REM stage, W/M: electric activity consistent with movement, low: low amplitude voltage. EEG Delta Power and metabolic rate in ‘Ju’, before and during arousal. Figure 3 illustrates the continuous transition from relatively high Delta Power to the state of monotonous ultra-low voltage EEG, which occurs during torpor. During the entry into torpor, the EEG gradually transitioned from a pattern of non-REM sleep until achieving a sustained ultra-low voltage state. Because the transition is very gradual, the end of sleep and the beginning of torpor is rather arbitrary. It ranges from up to 5000 μV2 during the periods of arousal to remaining consistently under 10 μV2 throughout the periods of torpor. Metabolic rates during the first evidence of sleep is much higher than at the end, and non- REM sleep precedes REM at the onset of the arousal and follows REM-like states at the end (tables 4 Figure 1 EEG Profiles
