Chronic shifts in the length and phase of the light cycle increase intermittent alcohol drinking in C57BL/6J mice

Abstract

It is possible to model CD effects on alcohol intake in C57BL/6J mice using a pattern of phase shifts and changes in the photoperiod. Using this model, we demonstrate that mice begin intermittent drinking during CD, and this increase in alcohol intake does not correlate with an increase in overall activity or in overall fluid intake.
