Fig. 6. Multiple flashes from individual cells of Lingulodinium polyedrum strain HJ. Data were collected for cells that flashed three or four times at v_max=5.7, 11 and 15 mm s^–1. (A) Duration of each flash as a function of flash number. Values are means ± s.d. (N=98 for flashes one to three; N=11 for flash four). (B) Length of interval between consecutive flashes. Values are means ± s.d. (N=98 for the intervals between the first and second and between the second and third flashes; N=11 for the interval between the third and fourth flashes).
