You know, those are all great questions, and we can't answer any of them accurately with our small sample. We said before that we need about 200 brains in order to answer those questions. There are some big gaps in our knowledge. For example, we just received the first woman's brain. All 44 of the other brains we have accumulated over the past 10 years have been male, and that's the same with most registries: there's a real lack of women's brains. We put out a big advertising campaign to try to get women to donate their brains, ultimately, when they're finished with them, to give them to us for science.
