The chemical that is the cause of so much woe is known as macrophage migration inhibitory factor or MIF, a protein found in the immune system that seems to help sperm cells grow .
If dopamine receptors are the gas, the brain's own inhibitory systems act as the brakes.
Earlier studies in rats had shown that animals that tend to explore and take more risks in new environments also tend to have fewer of these inhibitory receptors, and Zald wanted .
Arg-Phe-amide-related peptides influence gonadotropin-releasing hormone neurons ( Neural Regeneration Research ) During the last decade, our understanding of this hypothalamus-pituitary-gonadal axis has quickly expanded. Two novel hypothalamic Arg-Phe-amide-related peptides, kisspeptin and gonadotropin-inhibitory hormone, may be important regulators of the reproductive axis.

Steven Hill in WWL It also has and appears to have, from a number of studies throughout the world, an inhibitory, a direct inhibitory effect on a variety of malignancies,says Dr. Steven Hill, a Molecular Endocrinologist at Tulane.
Sandra Steingraber in E/The Environmental Magazine Melatonin is the body's internal clock, as well as its internal calendar,says Steingraber. "It's an inhibitory signal for puberty so the more melatonin you have, the later you go into puberty."
Susan Blackmore in The Australian The inhibitory neurons in the brain are very sensitive to oxygen and electrolyte changes,says Blackmore. "I believe this can disinhibit the brain and lead to the feelings of freedom commonly associated with NDEs."
