I have found two fascinating papers about modeling of moth olfactory network.
Model uses Hebbian plasticity and was calibrated on in vivo data.
Research includes model of mushroom body where sparsity and randomness play a critical role.
One of the interesting parts in model is the role of octopamine stimulation for learning.
What do you think about sparsity and memory representation in insects mushroom body?
Could you describe major differences in memory representation in neocortex and mushroom body?
Do you have experiments with neuromodulators in HTM model?
