Rodrigo, if I may suggest, calling what the amygdala does as
"perceptual" may confound things a bit. In Cognitive Psychology,
"perceptual" is used to denote functions performed very close to
the cognitive level that you mention. In fact, many scientists use
perception as an important part of our cognition (a position that
I agree).

As another point, if you're studying emotions and robotic
implementations, I think you should take a look at Aaron Sloman's


Prof. Sloman is one of the greatest authorities in AI and emotion
modeling and heads the Cognition and Affect Project, Univ. Birmingham.
