We discuss methods for fast spatiotemporal smoothing of calcium signals in dendritic trees, given single-trial, spatially localized imaging data obtained via multi-photon microscopy. By analyzing the dynamics of calcium binding to probe molecules and the effects of the imaging procedure, we show that calcium concentration can be estimated up to an affine(More)
Zinc is one of the most abundant transition metals in the brain, being present in a variety of synaptic processes. The mossy fiber terminals in area CA3 of the hippocampus contain large amounts of vesicular zinc and have an extremely high density of ATP-sensitive potassium (KATP) channels. The activation of these channels by zinc leads to rapid(More)
