a Change of the recording mode. To-and-from bidirectional recording mode are implemented. b 4D time-lapse imaging of a GCaMp6f expressed Medaka embryo (1 dpf). Fluorescent signals propagating over the outer layer surrounding whole embryos are indicated. Bottom-right images are two-dimensionally projected maps of the signal using the Mollweide cartography technique. c Plot of the GCaMP6f signal in a small ROI as a function of time. a.u. arbitrary unit. d Fourier analysis of the oscillatory expression of the GCaMP6f signal. a.u., arbitrary unit.
