Aggression Quote by Robert M. Sapolsky
““Moving beyond mere correlation, if you lesion the amygdala in an animal, rates of aggression decline. The same occurs transiently when you temporarily silence the amygdala by injecting Novocain into it. Conversely, implanting electrodes that stimulate neurons there, or spritzing in excitatory neurotransmitters (stay tuned), triggers aggression.4””

![“Now they [the Powers] have started the aggression, and the extinction of our nation is imminent. If we just fold our arms and yield to them, I would have no face to see our ancestors after death.
