Loss of appetite observed during sickness is attributed to the proinflammatory cytokine IL-18, which has been shown in experimental studies in the mouse to decrease food intake by acting on neurons of the bed nucleus of the stria terminalis, a component of extended amygdala, to influence feeding via its projections to the lateral hypothalamus (14). There is bidirectional flow of information between the ENS and CNS and between the ENS and sympathetic prevertebral ganglia, but the relative roles of the ENS and CNS differ considerably along the digestive tract.
