I commend you for your accomplishment, and sure you agree there is a difference between the basal ganglia, the limbic system, and the neocortex. We could go on about the functions and sub-divisions of each, but I stand by that without conscience (mind) stimuli, the body continues to process the precursor hormone of cholesterol into the following as simplified below:
Estrogen.
Progesterone.
Prolactin.
Testosterone.
Serotonin.
Cortisol.
Understood that some have their own sub-hormones like Estradiol.
There are many types of hormones. Not all are lipid or cholesterol based.
