The corticothalamic feedback and the thalamic reticular nucleus have gained much attention lately because of their integrative and modulatory functions. A previous study by the author suggested that this circuitry can process analogies (i.e., the analogy hypothesis). In this paper, the proposed model was implemented as a network of leaky integrate-and-fire neurons to test the analogy hypothesis. The previous proposal required specific delay and temporal dynamics, and the implemented network tuned accordingly functioned as predicted. Further-more, these specific conditions turn out to be consistent with experimental data, suggesting that a further investigation of the thalamocortical circuit within the analogical framework may be worthwhile.
