I've long been interested in circadian rhythms and recently came across a variety of articles that appear to indicate that the following neurotransmitters, transferases and hormones are connected. There are mentions of some circadian rhythmicity and maintaining homeostasis for these compounds(Are serotonin levels in humans affected by light?):

Additionally, their expression is related to Suprachiasmatic Nucleus and light exposure.

I'm interested if there's a good article or a talk that discusses the homeostatic system that those compounds are a part of. I'm particularly interested in their effect on the feeling of well being.

It seems to me that all these compounds are in some way related to moving and feeding. However, I cannot wrap my mind around multiple separate articles that describe how, and am looking for a single paper that may shed light on the connection between these compounds.
