Yeah, it seems possible, my experience with it is through seizures though. I've had a bunch of temporal lobe seizures (the general area which the article says this neuron superhub lies), and it seems like this superhub malfunctions and sends and receives signals to every part of my brain. My entire subconscious bubbles up at once with no filter. I can feel my heartbeat, I can feel my breathing, I can feel every nerve in my body but the feelings don't make sense, memories from years ago flood my brain, I have simultaneous multiple inner dialogues, I see everything in whatever environment I'm in but I'm confused, I have no idea what I'm doing. My brain then starts to shut down after a few seconds of this, or at least my memory does. The seizure either spreads into a grand mal or stops. It's really overwhelming. Anyway, it feels like these disparate parts of the brain are all working at once but the overarching controller malfunctions.
