Spiral (di-4-ANEPPS)

This image is recorded using voltage sensitive dye di-4-ANEPPS. The animated gif on the right shows a double armed spiral with an average period of 0.7 seconds. This is an example of a 'figure of 8' spiral wave.




The animated gif image on the right may not be playing the correct speed. For a relatively accurate sample, download the .avi (Windows movie format). The .mpg format plays back faster than real time.
