It shines infrared light into the brain and then it can measure basically blood oxygenation levels in a similar way to MRI.
And this is mobile.
People can wear this with like a little backpack and we can have them walk in natural environments versus urban environments.
And I'm interested in that.
We've started to do that.
I think, you know, we know a lot.
You know, the fact that we know that people's backwards digit span performance is changing after the walk in nature versus the urban walk, we know something's happening in the brain there.
The question there is, okay, so what more do we need to know?
Like, does it matter?
And I think...
It does, but we have to think a little bit deeply.
It's not going to be satisfying if I put people in an MRI scanner and show them nature pictures versus urban pictures, I'll find differences.
But what's causing the differences?
There's many, many features that differ between the images.
The nature images have different fractalness, different entropy, different amounts of curved edges, different color palettes.
So it's hard to zero in on what's causing the differences.
And then
If we find those features, is that the thing that's actually causing the changes in performance?
It's not clear.
I'm very eager to bring more neuroscience in, but we have to think hard about it.
