i think that those kinds of things and again this is part of the reason is that in the images we see areas of good blood flow of poor blood flow we might even see areas of temporal variations in blood flow we can see edema we can see a lot of different things we may be able to define habitats and and again not we won't see the the cells but we can see them indirectly in the sense that we know that for example in an area that where the blood flow is varying frequently that there's certain types of pheno there's certain phenotypes they're going to be adapting to that environment and so we can at least make that much extrapolation and make those kinds of suggestions
