From: Influence of light/dark cycle and orexins on breathing control in green iguanas (Iguana iguana)
ORX-A plasma levels throughout the day. Variation during 24 h of the plasma levels of ORX-A in the green iguana (values represented as means ± s.e.m.). The yellow bars represent the light phase, while the blue bars represent the dark phase. Different letters mean significant statistical difference, and same letters mean that the difference is not statistically significant. Number of animals: 4 for each time of the day (total: 24).
