H. Lach et Z. Srebro, CHRONOPHYSIOLOGIC ANALYSIS OF THE CIRCADIAN LOCOMOTOR-ACTIVITY OF MICE AND THE EFFECT OF NEUROPEPTIDE-Y ADMINISTRATION, Acta Biologica Cracoviensia. Series Zoologia, 38, 1996, pp. 19-22
Neuropeptide Y stabilizes the locomotor activity of animals kept under

nstant light than in constant darkness. The 12:12 light-dark regimen f
avours the effect of the peptide in augmenting phase differences in co
mparison with control animals.
