1. The nervous mechanism controlling feeding in the blowfly has been re-investigated.

2. The data presented reveal that the mechanism is more complex than originally thought but can be readily understood in the same basic terms as the original model, that is, the interaction of peripheral sensory excitation and internal inhibition.

3. The old model becomes the new by the addition of two new sources of internal inhibition--body-wall stretch receptors and a thoracic ganglion locomotor centre.

4. The several sources of internal inhibition are not equal in their inhibitory effect; removing body-wall stretch receptors produces a more vigorous hyperphagia than removing the foregut stretch receptor.
