| Popis: | It is known that laser light scattered from small particles in Brownian motion is noisy. When locust ganglia are illuminated by laser light we find that the scattered light is particularly noisy and the ganglia appearing to twinkle in that light, when the bathing medium is K + -rich. The effect is dependent on the presence of Ca 2+ and it is suggested that K + -rich solutions in the presence of Ca 2+ permit presynaptic vesicles to undergo Brownian movement. |
