There are 30 color combinations, unique prints like zebra and puzzle pieces, and even a few product suggestions for your next event. What we can do and what we cannot do with fMRI. Some of them are later classified as nonepileptic, which gives us access to undamaged tissue and we do not record pathological activity [. Below, you’ll find over 1,000 causes represented by a total of 65 different colors.
