 I find that ketamine creates a little bit of a window where one isn't assaulted by depressive ruminations. There's this neural network in our brain. It's called the default mode network. And it's that part of our brain that gets activated whenever we're doing purposeless activity, right? If I'm just like looking off in the distance, or if I'm driving home from work and just kind of like disconnecting, that default mode network is the thing that gets online.
