Dynamic Phenomena in Cells

Over the past several decades, progress in the measurement of rates and interactions of molecular and cellular processes has initiated a revolution in our understanding of dynamic phenomena in cells. Spikes or bursts of plasma membrane electrical activity or intracellular signaling via receptors, second messengers, or other networked biochemical pathways in single cells, or more complex processes that involve small clusters of cells, organelles, or groups of neurons, are examples of the complex behaviors that we know take place on the cellular scale. The vast amount of quantitative information uncovered in recent years, leveraged by the intricate mechanisms already shown to exist, results in an array of possibilities that makes it quite hard to evaluate new hypotheses on an intuitive basis. Using mathematical analysis and computer simulation we can show that some seemingly reasonable hypotheses are not possible. Analysis and simulations that confirm that a given hypothesis is reasonable can often result in quantitative predictions for further experimental exploration. Rapid advances in computer hardware and software technology combined with pioneering work giving structure to the interface between mathematics and biology have put the ability to test hypotheses and evaluate mechanisms with simulations within the reach of all cell biologists and neuroscientists.
