[The participation of the endogenous opioid system in regulating the feeding and protective behaviors of the mollusk Lymnaea stagnalis].
Opioids are known to influence feeding behaviour in the land snail. We have found this to be the case in the pond snail Lymnaea stagnalis, i.e. morphine increases while naloxone decreases food consumption. Evidence is presented that the feeding program is influenced by opiates indirectly. The endogenous opioid system seems to control directly a defensive fixed motor action accompanied by an arrest of feeding activity.
