• Continuous Hopfield network.

• Delay connections.

• Micro-object units have relative phase angles. MOUs with similar phase angles represent the "same" object.

• Micro-relation units associate groups of MOUs with their two micro-roles. MRUs are activated to the extent that the inputs to their micro-roles are out-of-phase.

• MRUs can be connected to one another. The connections represent both degree of association and one of the two possible mappings between the micro-roles.

• Contrastive Hebbian learning.
