It is apparent that the action of 4-aminopyridine, at concentrations of 0.1 to 1 mM, when examined in isolation from other experimental manipulations, is to cause a greatly enhanced probability of release at times subsequent to the time over which release normally occurs.
Lorsqu'on l'examine isolément, à des concentrations de 0,1–1 mM, la 4-aminopyridine a manifestement pour effet d'augmenter nettement la probabilité de libération au-delà de la période normale de libération.
