Photolytic uncaging
WebMay 1, 2007 · Ca(2+) rises evoked by photolytic uncaging of IP(3) showed the same distribution, suggesting that IP(3)-sensitive Ca(2+) stores are preferentially located in the soma and proximal dendrites. This distribution of metabotropic-mediated store release suggests that the neuromodulatory role of metabotropic receptor stimulation in BLA … WebFeb 1, 2006 · Similar to photolytic uncaging experiments, intracellular Ca 2+ concentrations could be elevated to produce a whole cell Ca 2+ rise, but without the requirement for caged Ca 2+. Irradiation of subcellular volumes in the soma or in PC12 neurites generated a relatively slow calcium rise (speed ∼20 µm/s). Less frequently, a fast calcium rise ...
