[Translate to English:] Legend: The six days old larval zebrafish expresses a fluorescent calcium reporter in all of its neurons, including in the enteric nervous system that regulates the gut. We use this transparent animal to image in vivo the activity of its neurons. Arrows indicate the rostral, dorsal, caudal, and ventral directions. Scale bar is 100 um.
Video legend: Live imaging of the activity of neurons in the guts of a six days old larval zebrafish, we can see the high motility of the guts driven by the waves of neuronal activity.
