Additional file 7: of Ancient role of vasopressin/oxytocin-type neuropeptides as regulators of feeding revealed in an echinoderm

Video recording showing asterotocin-induced cardiac stomach eversion in A. rubens. The video on the left shows that no cardiac stomach eversion is observed in a control animal that had been injected with 10 μl water. The video on the right shows that cardiac stomach eversion is observed in an animal that had been injected with 10 μl of 10−3 M asterotocin. These videos are representative of the experiments shown in Fig. 8, and static images from these videos are shown in Fig. 8c. The original video recordings were 12 min in length, and these were then sped up to 45-s videos and combined into a single file using Final Cut Pro software. (MP4 12041 kb)
