What does the verb 'do' mean in this sentence? I select it in bold.
The brain is an amazing and complex organ. And while many people are fascinated by the brain, they can't really tell you that much about the properties about how the brain works because we don't teach neuroscience in schools. And one of the reasons why is that the equipment is so complex and so expensive that it's really only done at major universities and large institutions. And so in order to be able to access the brain, you really need to dedicate your life and spend six and a half years as a graduate student just to become a neuroscientist to get access to these tools.
