Functions of the amygdala : more diverse than previously thought
Science in general, and neuroscience in particular, are constantly evolving. So even though our knowledge of a given brain structure may not have undergone a scientific revolution or a paradigm shift at any given time, when we compare what we know about it now with what we knew, say, 10 years ago, we may find that things have changed a lot.
