Use it or lose it: How neurogenesis keeps the brain fit

A 40 page accepted manuscript in
Behavioural Brain Research
I like these two points, hope someone researches them:

• Immature neurons are needed for some types of complex learning
• Immature neurons might be recruited into existing neural networks via oscillatory activity

I do like the description on page 4 on what is needed, effortful learning of the new neurons to keep them alive. And if we could just get this matched to the migrating neurons from here:

How do we get angiogenesis to supply these new neurons with blood?
