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. So initially, this is what we see once we bleach it, we see this purple spots, let's say it's purple. And then over time, this purple spot disappears because these bleached purple molecules essentially move away. And so the fluorescence actually is recovered.
