Quizplus · Accepted Answer

The OVLT (organum vasculosum of the lamina terminalis) and subfornical organ (SFO) are two areas in the brain that are important for detecting the osmotic pressure and salt content of the blood. These areas are located in the hypothalamus and are considered to be part of the "thirst center" in the brain. The substantia nigra and red nucleus are involved in movement control and the ventromedial hypothalamus is important for regulating feeding behavior.
