Two-timescale learning in thalamocortical structures. We propose that one can learn the thalamocortical structure to enable meta-learning by applying the general network motif in two different timescales. First, one can learn the corticothalamic connections by applying the motif on the blue loop with a faster timescale. This allows the network to consolidate flexible switching behaviors. Second, one can learn the cortical connections by applying the motif on the orange loop in a slower timescale. This allows cortical neurons to develop a task-relevant shared representation that can generalize across contexts.
