Activity patterns of diurnal drinking behavior in male mice [Mus musculus]

Activity patterns of diurnal drinking behavior in male mice aged 12 to 20 weeks of IVCS, C3H/He and C57BL/6 strain were investigated in 14: 10 light-dark cycle. Drinking behavior activity of the mice synchronized with the light-dark alternation, thus showing regular 24-hr rhythms. The activity pattern of drinking behavior differed considerably among three strains. The highest activity of drinking behavior in IVCS mice was recorded around the time for lighting on and off, while in C3H/He and C57BL/6 mice it tended to be shown in the dark phase.
