Overview of Session IV: Interactions between Hormones and Neurotransmitters in The Control of Peptidergic Neurons
Drs. Fuxe and McCann have discussed many aspects of neurotransmitter systems in the control of anterior pituitary function. It is apparent that acetylcholine, catecholamines, serotonin, histamine and GABA and their receptor stimulants or agonists, receptor blockers and synthesis inhibitors can stimulate or inhibit the secretion of many pituitary tropic hormones by influencing, in most cases, the secretion of peptide releasing hormones from hypothalamic neurons. The effects of catecholamines on gonadotropic function have been most thoroughly studied and perhaps for that reason have been the most controversial. Specifically, the most unresolved problem is the influence of dopamine on LHRH; everyone agrees that it inhibits prolactin secretion and many consider it PIF itself.
