Quizplus · Accepted Answer

The OVLT (organum vasculosum of the lamina terminalis) and the subfornical organ are the regions in the brain that are primarily responsible for detecting changes in osmotic pressure. They are parts of the brain's circumventricular organs, which are specialized structures located in the walls of the third and fourth ventricles that lack a blood-brain barrier. The ventromedial hypothalamus is involved in regulating hunger and satiety, while the substantia nigra and red nucleus are primarily associated with motor function.
