The time course of the action of Bleb. a Time course of the suppression of contraction-related signals. The size of the normalized contraction-related signal (fractional changes in transmitted light) is plotted as a function of time after the application of Bleb. Open circles Data were obtained from a pixel of a preparation, and the concentration of Bleb was 10 μM. Filled circles Data were obtained from a pixel of another preparation, and the Bleb concentration was 100 μM. b The time course of the amplitude of the optical action potential. The concentration of Bleb was 100 μM. The dotted line indicates the mean value of the amplitude
