Fig. 4

Ca²⁺ spikes are expressed both in the axon and soma of developing CaPs. (A and B) GCaMP3 activity acquired at 7.6 Hz in a single CaP of a single double-transgenic Hb9:Gal4/UAS:GCaMP3 embryo at 18 and 24 hpf. Dorsal is to the top and rostral is to the left. Fluorescence intensity is displayed on a pseudocolor scale like in Fig. 2. Dotted line indicates the HMS. (C and D) Time course of GCaMP3 activity in three regions (distal axon is blue, proximal axon is orange, and soma is magenta) from the same neuron. Intensity traces for regions identified by arrows are plotted as a function of time. The boxed regions in C Left and D Left are plotted in C Right and D Right, respectively. Fluorescence intensity was normalized to baseline. Dashed lines are the same as in Fig. 3. n = 50 spikes from 12 embryos (18 hpf), and n = 50 spikes from 5 embryos (24 hpf).
