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: Opet, radeći nagore, od 60-ih i 70-ih godina smo pokušavali, takođe očajnički, da isključimo molekule koji deluju između nervnih ćelija - serotonin, dopamin - i pokušavali da tako izlečimo depresiju, i to je uspevalo, ali je onda doseglo granicu.
