#12I appreciate the suggestion, but how am I supposed to do that?

Adult neurogenesis in rats was my thesis focus, so it's interesting that all the rat work we did may or may not translate over to humans.

#15I'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?

Neurogenesis in the hippocampus and olfactory bulbs is ongoing trough the lifespan. I am presuming this is not about that neurogenesis.

#18Absolute pitch is something that supposedly can only be learned before the age of 6 but the drug Valproate seems to reopen this window. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3848041/

Actually, that's exactly what they're claiming to refute: > A small number of papers had indicated that humans also possessed this capability, specifically in an interior region of the brain known as the hippocampus, which is associated with memory. > A team from UC San Francisco had hoped to see evidence of this neurogenesis in action. > Team members examined brain tissue samples collected from 59 human subjects who…

I learned it as a teenager and lost it in my 20s. Like anything I learned it through practice and familiarity. Once I stopped working in music production I slowly lost my absolute pitch too. Similar to the way I used to be able to speak French but now can only string a few words together.
I've been with my (German) girlfriend for about a year now, and have visited her family in Germany a couple of times. It has really made me realize how much of my ability to put together a sentence in German has simply vanished over the last 15-16 years. I'm boning up using Duolingo now, because I really want to be able to have a full conversation with her (not very English speaking) family.
