The Recurrence of Eating in Rats after apparent Satiation.

Authors


Summary

An attempt has been made to discover whether eating can be made to recur after the animal is satiated with food. This has been found to be the case under certain rather complicated conditions, the essential feature apparently being that the conditions arouse a certain state of excitement in the animals. It, was discovered, further, that those conditions which will start eating after satiation will prevent it when the animals are hungry.

It is suggested that. this is similar to the Pavlovian “external inhibition” and “dismhibition” respectively. From this it is concluded that satiation must involve some mechanism similar to Pavlov's “internal inhibition.”
