Listen, folks, we’ve got something incredible here, really fantastic. Hemispatial neglect, it’s a big deal, okay? People aren’t paying attention to one side, and it’s a problem. But there’s been a lot of talk, a lot of noise, conflicting information about what’s causing it. They say it’s the right parietal lobe, the attention networks, but we need to get to the bottom of it, we need to do it right.
So, what we did, we took a huge look at all the MRI studies out there. We’re talking meta-analysis, very smart, very sophisticated. And we found these regions in the brain, 13 of them, all in the right hemisphere, that are connected to neglect. We mapped them out, we checked the connections, and guess what? The superior longitudinal fasciculus, the SLF, it’s a big player, connecting a network that’s just huge – fronto-parietal-temporal, very important.
And the attention networks, they’re involved too, but it’s not just them. It’s bigger than that. We’re looking at higher-order networks, a lot of them. Our model, it’s the best, really top-notch. It shows you exactly where and how these networks come together for the functions that go haywire in neglect. It’s all about that fronto-parietal-temporal network, connected by the SLF, and it’s going to change the game, believe me.
