Alkali metal cations: effects on isolation-induced aggression in the mouse

Abstract

Alkali metal cations were given in varying doses over 14 days to CF-1, male mice, isolated for 4 weeks prior to testing for isolation-induced fighting. Lithium and cesium in doses of 4.5 and 6.0 meq/kg reduced the duration of isolation-induced aggression in a 15 min test period when compared with controls. Toxicity was evident in the cesium-treated, but not the lithium-treated mice. No enhancement of aggression was seen in the rubidium-treated group.
