Transglial calcium waves in BG imaged with G-CaMP2 in vivo. (A) (Left) Maximum brightness side projections of DsRed expression after infection of the mouse cerebellum with an adenovirus carrying the sequence for the fusion protein G-CaMP2_DsRed. (Bottom Left) Molecular layer section showing BG processes. (Right) x–y sections at different levels below pia mater show extent and branching of a single BG. (B) Radial wave measured with G-CaMP2 in the molecular layer. (C) A transglial wave domain. (D) Orientation of domains relative to the parallel fiber axis. (E) Distribution of domain sizes relative to a single BG.
