中文摘要 | 日週律動是由內在大約24小時震盪器,來掌握著不同行為及生理功能。它的規律性是受外界光週期的影響,而且與之同步。在全暗自由律動的條件下,有些規律性的參數,例如自由律動週期與波動形式,顯示在進入全暗環境之前的光週期有長效性的作用,對自由律動週期的影響,稱為後續效應,被認為是對光週期的穩定導引作用。而光週期對波動形式的調控,也是對季節性改變的光週期,做出適當的同步現象。波動形式的調控,呈現相當高的相似性,隱含著對光週期時間量測機制的參與。這類經歷依變的機制仍待研究。 |
英文摘要 | Circadian rhythms are endogenous, ~24-h oscillations governing various behavioral and physiological functions. The rhythm synchronizes to and is profoundly affected by light cycles. In free-running conditions under constant darkness, some parameters of the rhythm such as the free-running period and waveform show long-lasting changes caused by lighting conditions given before transfer to constant darkness. The change in the free-running period is called the after-effects and is thought to contribute to stable entrainment to the light cycle. Photoperiodic modulation of the waveform also contributes to appropriate synchronization to seasonally changing photoperiods. Considerable similarity of the waveform modulation to photoperiodic responses implies its involvement in the photoperiodic time measurement mechanism. The mechanism for these history-dependent changes has yet to be elucidated. |
