Conversely, serotonin activates when food is consumed, inducing rest and indicating satiation. This fundamental interaction between dopamine as the pursuit chemical and serotonin as the satiation chemical has evolved over millions of years but retains its core function in governing behaviors related to food acquisition and consumption. This duality can also be noted in modern devices like the Roomba, which reflects similar algorithms in their operational design.
