I’ve never heard of “newborn neurons generated by exercise”. I wonder what they mean.

I don't know what they mean here, but I have seen numerous studies that say that HIIT changes a body down to the cellular level, actually improving and even adding new mitochondria (improving autophagy), and possibly building new neural pathways.

I would suggest ignoring those details and just focusing on the results for your particular brain.

I’m taking a mushroom extract that increases nerve growth factor. Maybe high-intensity exercise does the same.
