The cessation of transient fluctuations in the concentration of intracellular calcium halts the migration of granule cells in the developing cerebellum, according to an article in the Proceedings of ...

Left: A blue light pulse of 0.1 seconds triggers a calcium signal (red) in guard cells, which is followed by an anion current (black). Right: The influx of calcium into the cell promotes the release ...

Researchers have developed a novel method for simultaneously recording action potentials (APs)—temporary changes in electrical potential when cells become excited—and calcium transients—calcium ...
