Entrainment of a circadian pacemaker by brief light pulses

I. The empirical basis of a model – by C.S.Pitendrigh

II. Criteria for stable entrainment – by E.A.Ottesen, C.S.Pittendrigh, S.Daan

2 complete manuscripts from the 1970’s explaining empirical basis and modeling predictions of Pittendrighs model on non-parametric entrainment of Drosophila eclosion rhythms. The manuscripts were intended for submission to The American Naturalist, but this never happened. A third manuscript in the series (III. Experimental tests of the model – by C.S.Pittendrigh et al.) did not reach completion. I and II have been transcribed to Word by Michael Tackenberg in 2015
