By chance or by the clock: How do concentrations in cells oscillate? — •Martin Falcke and Alexander Skupin — Abteilung Theorie SF5, Hahn Meitner Institut, Berlin
Intracellular concentration oscillations can be deterministic limit cycle oscillations or can be driven by fluctuations in a non-oscillatory dynamic regime. The cause of oscillations of intracellular Ca2+ concentrations was discussed on theoretical grounds in the last 2-4 years. We present experimental data very much in favor of one of the mechanisms and substantiate them with theoretical results.
