Features：Researchers explored topological inversion and soma-targeting strategies, designing a red gene-encoded calcium ion indicator—FRCaMPi(for enhanced in vivo performance). It demonstrated up to 2-fold higher dynamic range and single action potential (AP) peak ΔF/F0 compared to the widely used jRGECO1a in cultured neurons and in vivo experiments.
