Movies of Phenomena in the Chick Embryo

Spiking in Renshaw-like interneurons captured via video-rate microscopy of calcium transients. (Cell bodies were retrogradely filled with a Ca2+ sensitive dye and activated by antridromic stimulation of muscle nerves).
Episodic bouts of kicking owing to spontaneous network activity (SNA) in a live chick embryo (mid-gestation).
