Learn the difference between positive and negative feedback. Understand what is positive feedback in biology through the use of some positive...
Positive feedback systems are unusual in biology, as they terminate with some cataclysmic, explosive event. A good example of a positive feedback system involves oxytocin and its other effect: causing contraction of uterine muscle during childbirth (Fig. 1.51). In this case the stimulus for ...

Systems Biology Meets Single-Cell Physiology: Role of a Positive-Feedback Signal Transduction Network in Cerebellar Long-Term Synaptic Depression 来自 Springer 喜欢 0 阅读量: 28 作者:K Tanaka,GJ Augustine 摘要: It is widely assumed that persistent changes in the brain, such as those occurring ...
Here we provide a mathematical analysis of arbitrary length positive feedback loops with protein production and degradation. These loops serve as anion of typical regulation patterns in protein signalling pathways. We first perform a steady state analysis and, independently of the chain length, ...
Therefore, the LTP can be considered as a chain of biochemical reactions with a positive feedback loop. In this study, we investigated numerically the role of interactions in a chain of biochemical reactions with a positive feedback on the bistable behavior or memory. We conclude that the ...

Third, experience also caused some of the between-individual differences in problem-solving performance, and since experience is not reversible, and by definition carries forward into the next stage of the sequential problem-solving process, this suggests a positive feedback loop driving consistency ...
