Pittendrigh, GS (English spelling) PittendrighGS

…However, the results of low-temperature treatment and anaerobic treatment, which also cut off the energy supply, did not necessarily match. GSPittendrigh proposed a two-oscillator model consisting of an A oscillator that is sensitive to light and an B oscillator that is sensitive to temperature and directly connected to the rhythmic phenomenon, because the eclosion rhythm of Drosophila is affected by temperature changes and light interruptions. He thought that the reason it took several cycles for the rhythm to stabilize at a new phase in the light interruption experiment was because first the A oscillator was set by the interrupted light, and then it took several cycles for the B oscillator to follow it. …

…しかし，同様にエネルギー供給を断つ低温処理と嫌気処理とで結果は必ずしも一致しなかった。ピッテンドリクG.S.Pittendrighは，ショウジョウバエの羽化リズムが温度変化や光中断の影響を受けることから，光に敏感なA振動体と温度に敏感でリズム現象に直結したB振動体からなる二振動体モデルを提唱した。光中断実験でリズムが新しい位相に安定するまで数サイクルを要するのは，まずA振動体が中断光でセットされつぎにB振動体がこれに従うのに数サイクルかかるためと考えた。…
