Abstract
Homing pigeon releases from three different sites were performed to compare the effect of naloxone injection with that of exposure to an oscillating magnetic field. A similar modification of initial orientation was observed. This result raises the question whether alterations in initial orientation can be related to the activity of the endogenous opioid system.
Riassunto
In rilasci di colombi viaggiatori effettuati da tre località diverse è stato osservato che un trattamento con naloxone ha, sulľrorientamento iniziale, un effetto simile alla permanenza in un campo magnetico irregolarmente oscillante. Ciò induce a considerare la possibilità che certi trattamenti magnetic! possano indurre variazioni nelľattivita del sistema degli oppiacei endogeni.
