In the insect brain, dopamine-releasing nerve cells are crucial to the formation of both punished, rewarded memories
Children quickly learn to avoid negative situations and seek positive ones. But humans are not the only species capable of remembering positive and negative events; even the small brain of a fruit fly has ...
