High Ca2+ is indicated in red while low calcium is in blue. Large panel is an expanded view showing the freely-moving animal that has been contrast enhanced to make the worm and its laid eggs visible. Inset is cropped to a small area containing the vulval muscles, and stabilized to remove movement. Text labels indicate when Ca2+ transients and egg release occur.
