Does Lsd shrink amygdala permanently?

Does Lsd shrink amygdala permanently or does it go back to normal if you havent tripped in a while?

I think it does cause neurogenesis, never heard of psychs causing shrinkage.
But if you have a bad trip I would imagine it would become more active tbh, and you might become scared all the time.
