#3I'm gonna wait for the replication, as always.
But what about all that exercise-induced BDNF-mediated neurogenesis stuff? Was that only observed in mouse models?

#4I thought they used isotope analysis from nuclear testing fallout to prove that the neurons in the brain are between 15-20 years old on average? How do they reconcile this?

A likely possibility: the molecules get replaced, but it's still the same cell.

#8I appreciate the suggestion, but how am I supposed to do that?
