Abstract
Mutual relation in inducing convulsion between 2 or among 3 El-mice were brought to a conclusion from many cases, and it was found that there was a reasonable relationship between the simultaneity and non-convulsion in El-convulsion.
The influence of centra l-acting drugs to the relation was investigated when El-mice were administered a little of the drug which dose not show general pharmacological actions at all.
In consequence, the simultaneity increased in administration of central stimulants, and to the contrary it decreased and the rate of non-convulsion increased in administration of central depressants.
However in administratio n of DL-amphetamine, the mutual relation between 2 El-mice went wide from the normal distribution area, besides focused upon a limited area.
