i think there's an easy answer - and by the way, your post got all
mushed because you put it all on one line! anyway -

In 1961, Downer did a commisurotomy and unilateral amygdalectomy, the idea 
being that stimuli presented to one eye could only be processed in the
ipsilateral visual cortex, ergo amygdala. The finding was that the monkey
didn't display normal fear reactions when stimuli were presented to the 
lesioned side. The reference is:

Downer, JDC (1961) Changes in visual gnostic function and emotional 
behaviour following unilateral temporal lobe damage in the "split-brain"
monkey. Nature, vol 191, p 50-51

for a book that probably has all of the other answers, check John 
Aggleton's "The Amygdala", 1992, Wiley -Liss inc.
Hope this helps!
