The amygdala would be an emergency type fast response parallel memory subsystem where good or (especially) bad can be stored as a property.

The amygdala is full of hardwired archetypes (genetically programmed) that are evaluated at a subconscious level. These programmed features are things like snakes, spiders, features of your own species, faces, secondary sexual characteristics, and the like. This is fed from a tap on the feed to the visual system and is mostly a one-way feed into the hippocampus.

This is the source of much of the good/bad signals.

More on the amygdala processing here:

Thoughts on multiple pathways for sensory input into the neocortex

It seems to be a thing for connectome/cortex researchers to ignore the processing that goes on in the “lower” brain structures. These were/are sufficient to run lizards and amphibians. There is absolutely no reason to think that they re not performing much of their original functions inside of the functioning brain. The lower brain receives a low-resolution image from the eye area “away” from the fovea and directs the eye to point at interesting areas to form identification of an object with a …

Some of the other good/bad features come from other limbic system nodes such as the hypothalamus.

I think that there may be a mechanism for adding new features to the amygdala based on the utility this function would add but I am unaware of any mechanism to do so.
