The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
The dentate gyrus does seem to be one region in the brain, certainly in the rodent brain, but more and more it's seeming also in the human brain where at least some new neurons are added throughout the lifespan. And, as it turns out, that cardiovascular exercise can increase the proliferation of new neurons in this structure.
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
But doing that for 180 to 200 minutes per week total is it appears the minimum threshold for enhancing some of the longevity effects associated with improvements in cardiovascular fitness and we believe that it is indirectly, I should say indirectly, through enhancements in cardiovascular fitness that there are improvements in hippocampal dentate gyrus neurogenesis.
but about 150, or maybe as much as 200 minutes of so-called zone 2 cardio per week, movement that you can just barely carry out a conversation, is going to be very useful.
that zone two training of course is going to be very powerful for the health and integrity of the cardiovascular system that's going to allow for the delivery of all these molecules and of course the delivery of blood flow itself to the brain because cerebral blood flow is Central to brain function
It's very clear that getting a minimum of 180 to 200 minutes of so-called zone 2 cardiovascular exercise. So this is cardiovascular exercise that can be performed at a pretty steady state. We believe that it is indirectly I should say indirectly through enhancements in cardiovascular fitness that there are improvements in hippocample dentate gyrus neurogenesis.
