Neurogeneisis need not necessarily be brand new neurons. It can mean the reestablishment of previous connections.
Neurogeneisis happens in all areas of the brain. In the pleasure centres of the brain too.
When you're depressed it may be from broken limbic circutry. When connections are restablished those feelings come back.
Its not the only theory.
But we know that growth factor injections produce similar AD effects (NT-3 NGF, BDNF, GDNF etc)
Did you see that 60minautes episode on parkinsons and GDNF, it was crazy. One guy coudn't move at all, but after 2 years on GDNF he was able to walk over and hope on a tractor to ride.
That is a parralell that I see to mood disorders. Depression is parkinsons of the limbic system, and those growth factors may be the best chance we have to walk again.
