Phototaxis in Chlamydomonas: The movie starts with cells being unstimulated and the time is displayed at the top in hours:minutes:seconds (00:00:00). When the hours go out, the cells are being stimulated from the left, when the minutes go out, the cells are stimulated from the right. After chasing the cells back and forth, they are photoshocked a few times. Quicktime Format MPG Format
