The emotional communication based on methamphetamine mortality as the index in olfactory bulbectomized mice

The emotional transmission was studied in olfactory bulbectomized mice by the communication box method using methamphetamine toxicity (mortality) as the index. Intraperitoneal administration of methamphetamine 15 mg/kg in the sender, responder and control groups of olfactory bulbectomized mice resulted in a marked rise of mortality in the sender and responder groups, compared to the control group. In the sham-operated mice, on the other hand, the mortality markedly rose in the sender group, but the mortality of the responder group was lower than that of the sender group, and was higher than that of the control group. As the result of studies on the emotional transmission using methamphetamine toxicity, the emotional reaction in the sender group appears to be transmitted to the responder group in olfactory bulbectomized animals.
