Expression patterns of G-CaMP7 (top, green), coexpressed DsRed2 (middle, red), and G-CaMP7 overlaid with DsRed2 and Hoechst nuclear counterstaining (bottom, blue) in adult TRE-G-CaMP7 \u00d7 CaMKII-tTA mice. Parasagittal sections cut at different mediolateral levels are shown from left to right.<\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Ca2+<\/sup> is an intracellular messenger that regulates cellular functions such as excitability, gene expression, secretion, and contraction. Genetically encoded calcium indicators (GECIs), such as GFP-based G-CaMPs, produce great changes in fluorescence in response to increases in intracellular Ca2+<\/sup> concentrations. Understanding brain function requires techniques for monitoring the patterns of activity in neuronal networks, and many transgenic mouse lines that express G-CaMPs in the brain have been reported. Hayashi and colleagues generated a new transgenic strain that expresses the improved G-CaMP variant G-CaMP7 [1] under a tetracycline response element (TRE) [2]. Crossing with tTA driver mice and doxycycline treatment results in cell type-specific and temporally controlled expression of G-CaMP7 in TRE-G-CaMP7 mice. These technical advances will provide a powerful approach for functional and pharmacological studies of neural circuit activity in vivo<\/i>..<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
