Amygdala using SPA Challenges

I was inspired by the amygdala models used in Terry Stewart’s model and the AmyRobot (linked below). Both examples utilize single value inputs collected into an array. The amygdala contains a lateral, small basal ganglia, and central sections. The transformations and functions performed with these models work well with data types. I want to create something similar, but I’d like to use semantic pointer elements to work with vocabularies instead of numbers.

If I use the existing framework as a model, I’m finding it hard to use SPA elements to produce similar effects. Has anyone attempted something similar to this before or can anyone recommend any guidance here?
