Abstract
Navicula reversing its direction of movement voluntarily (autonomic reversal rhythm); induced reversal on the boundary of a light trap (step-down reaction). Partial illumination (40 µm wide, moving light spot) of anterior and posterior cell poles and the middle of the cell prove that the poles are the sites of light preception. Red light, 670 nm; green safety light, 525 nm. Time-lapse.
