内容記述 | Optical methods for monitoring membrane potential with fast voltage-sensitive dyes have been introduced as a powerful tool for studying cardiac electrical functions. These methods offer two principal advantages over more conventional electrophysiological techniques. One is that it is possible to make optical recordings from very small cells which are inaccessible to microelectrode impalement, and the other is that multiple sites/regions of a preparation can be monitored simultaneously and provide spatially-resolved mapping of electrical activity. The former has made it possible to record spontaneous electrical activities in early embryonic pre-contractile hearts, and the later has been applied for the mapping of the propagation patterns of electrical activities in the cardiac tissue.
