Astrocyte Ca²⁺ signal is altered in G2-3 transgenic mice. a Pseudocolor images and representative traces of Ca²⁺ fluorescence intensities obtained from transgene negative (TgNg) and G2-3 mice. b Heat map indicating Ca²⁺ levels and raster plot indicating Ca²⁺ events along time obtained from TgNg and G2-3 mice. c Ca²⁺ events per minute obtained from TgNg and G2-3 mice in control conditions and in the presence of a cocktail of antagonists. d Ca²⁺ events per minute obtained from TgNg and G2-3 mice at different ages. Data are expressed as mean ± s.e.m. (**)p < 0.01, (***)p < 0.001
