Now, what exactly are we going to see? Well, if there was no movement and if the membrane was in fact a rigid and a static structure, then that means this area will remain bleached. But what happened is, because there is a lateral movement of these molecules, eventually these bleached molecules will disperse throughout that membrane. And what that means is, because these unbleached molecules will replace the bleached molecules in this area, that will recover the fluorescence in that particular area. So over time, the lateral movement of the lipids will disperse the non fluorescent, the bleached molecules. This will return that fluorescence to that initially bleached area.
