FIGURE 3

Effect of vagal nerve stimulation on leading pacemaker site of the zebrafish sinoatrial node (SAN). Schematic of the zebrafish isolated heart showing the location of the SAN and the intact left (LX) and right (RX) cardiac branches of the vagal nerve (A). The leading pacemaker site(s) measured in individual SAN before nerve stimulation (B,E), during left (LVNS, C) or right (RVNS, F) vagal nerve stimulation at 15 Hz, and during LVNS and RVNS after application of the nicotinic receptor blocker hexamethonium (D,G), projected onto a representative SAN image, with individual subjects differentiated by colour (n = 8).
