When sufficient food or substrates have been received and leptin is high, then the satiety center is stimulated and sends impulses that inhibit the feeding center . When insufficient food is present in the stomach and ghrelin levels are high, receptors in the hypothalamus initiate the sense of hunger . </Li> <Li> The thirst center operates similarly when certain cells in the hypothalamus are stimulated by the rising osmotic pressure of the extracellular fluid . If thirst is satisfied, osmotic pressure decreases . </Li> </Ul> </Li> <Ul> <Li> The feeding center or hunger center is responsible for the sensations that cause us to seek food .
