讲座题目: Generation of rhythmic activity in the pregnant uterus.
讲座摘要:

The generation of rhythmic contractions in the uterus shortly before delivery is a crucial aspect of birth. Surprisingly, the mechanism leading to contraction is not fully understood. Developing a better understanding of these scientific issues may provide help in devising treatment of prenatal birth, which is a leading cause in infant mortality. Scientifically, the question can be simply formulated: given that none of the isolated uterine cells, taken in isolation, is capable of oscillate, how can rhythmic activity be developed in a whole tissue ? The well-documented observation that intra-cellular coupling increases very significantly towards the end of pregnancy, provides a hint. Based on studies of mathematical models of uterine cells, I will present a plausible scenario leading from quiescent to spontaneously active tissue when the cellular coupling increases. This scenario involves interesting complex regimes of spatio-temporal activity through the tissue, which I will discuss.
