Local Ca(2+) signals through voltage-gated Ca(2+) channels (CaVs) drive synaptic transmission, neural plasticity, and cardiac contraction. Despite the importance of these events, the fundamental relationship between flux through a single CaV channel and the Ca(2+) signaling concentration within nanometers of its pore has resisted empirical determination, owing to limitations in the spatial resolution and specificity of fluorescence-based Ca(2+) measurements. Here, we exploited Ca(2+)-dependent i ...[more]
