english: Again, working upwards, since the 1960s and 1970s, we've tried, again, desperately to turn off molecules that operate between nerve cells -- serotonin, dopamine -- and tried to cure depression that way, and that's worked, but then that reached the limit.
non_english: Spet, če gradimo navzgor od 1960ih, 1970ih  smo skušali na vse načine ugasniti molekule, ki delujejo  med živčnimi celicami --serotonin, dopamin-- smo poskušali tako zdraviti depresijo, in je delovalo, ampak samo do neke mere.
