Fig. 10From: Evolutionary understanding of the conditions leading to estimation of behavioral properties through system dynamicsRepresentation of the circadian rhythm. Left = circadian process oscillation; right = temperature process oscillation between the circadian temperature (horizontal axis) and the body temperature (vertical axis). Note: this is a normalized rhythm despite the fact not all rhythms are identical. Our core body temperature is roughly linked to this cycle, with various hormones being released at certain stages during the rhythm because our body temperature reflects energy levelsBack to article page
